Texto completoIncludes bibliographical references (p. 95-98).
Automated unit tests are essential for the construction of reliable software, but writing them can be tedious. If the goal of test generation is to create a lasting unit test suite (and not just to optimize execution of system tests), it is essential that generated tests can be understood by the developers that will be running them, so that they can tell the difference between real and spurious failures. amock is a system which automatically generates human-readable JUnit regression tests that use mock objects to simulate the behavior of individual objects dynamically observed during a system test execution.

Texto completoThe main theme of this work concerns specification tests. What is meant by that is a set of procedures which has been used in the econometric literature since recent times and which allows validity or rejection of the specification hypothesis of a model : choice of variables, exogenous characteristics of some of them, choice of the dynamics structure. . . Rather than testing a hypothesis giving a specific value to parameters, one tries to find out whether the set of selected probabilities contains the "genuine" law from which data is issued. The work is organised in the following manner : - a theoretical section aimed at giving a rigorous framework where the main definitions concerning the specification of statistical model are presented within the privileged framework of a bayesian structure - a survey of recent literature on classical tests of specification with a special emphasis on their asymptotic properties. - a presentation of a bayesian approach of specification tests. - an example of application to a dynamical macro-economic model of the labour market in France in which exogeneity of the real salary is tested in the functions of labour search and supply

Texto completoThe purpose of this dissertation is to investigate how teachers perceive and work with the national tests in order to help students meet the goals of the course. Furthermore, due to our future careers as teachers, we want to gain more insight into the role national tests play in English. This is a qualitative study based on formal in-depth interviews that can provide a good understanding of the subject and of the informants’ views. As the teachers at secondary school work with national tests yearly they were best suited as interviewees in this investigation. Four interviews were carried out with teachers and they lasted approximately 40 minutes each.The interviews touched on a variety of questions ranging from how the teachers work with the national test and how they look upon the test, to how the purposes stipulated by Skolverket regarding the national test are fulfilled. The outcome of the interviews is that the national test in general facilitates more than complicates teachers’ work. The test serves as a good support when assessing and grading the students since it can confirm the teachers’ assessment of the students’ capability. However, this study also shows that the preparation methods used before the national test benefit weaker learners more than stronger ones.

Texto completoA atividade de Testes Aplicacionais é uma componente integrante do ciclo de desenvolvimento de uma aplicação. Inicialmente, esta tarefa estava intrinsecamente ligada à própria atividade de programação, não existindo uma definição propriamente dita. A sua evolução passou pelo desenvolvimento de técnicas, ferramentas e processos próprios que ainda hoje são alvo de melhoria. Nesta dissertação foi estudada a evolução dos Testes aplicacionais, o seu conceito, objetivos e tipos. Pretende-se demonstrar a importância dos Testes Aplicacionais, nomeadamente, dos Testes Funcionais e quais são os critérios de escolha de um método de Testes Funcionais adequado a um determinado negócio. Das pesquisas efetuadas foi elaborado uma revisão da literatura e para complementar foi efetuado um Estudo de Caso numa instituição bancária onde foi estudado o seu método de execução de Testes Funcionais. O principal resultado obtido foi a definição dos critérios de seleção de um método de Testes Funcionais. Esses critérios passam pela cultura da empresa, boas práticas, a tecnologia adotada, os custos e os próprios modelos de desenvolvimento de software.
Applicational Testing activity is an important component of the application development cycle. Initially this activity was intrinsically linked to the programming activity, but there wasn’t a specific definition. Its evolution passed through the development of techniques, tools and processes that today still are being improved. In this dissertation it was studied the Applicational Testing evolution, its concept, objectives and types. The focus of this study lies on Functional Tests, which are a type of Applicational Testing, and the respective methods. We intend to demonstrate the importance of Applicational Testing, mainly the Functional Testing and which are the criteria for choosing the appropriate method of Functional Tests that suits best for a particular business. For this research, a literature review was carried out, as well, in a banking institution a case study was elaborated in which their method of performing Functional Testing was studied. The main result that was bought about was the selection criteria for the functional testing method. Those criteria are: organizational culture, well-practice, the adopted technology, costs and the own models for software development.

This thesis contains three chapters. The first chapter considers tests of the parameter of an endogenous variable in an instrumental variables regression model. The focus is on one-sided conditional t-tests. Theoretical and numerical work shows that the conditional 2SLS and Fuller t-tests perform well even when instruments are weakly correlated with the endogenous variable. When the population F-statistic is as small as two, the power is reasonably close to the power envelopes for similar and non-similar tests which are invariant to rotation transformations of the instruments. This finding is surprising considering the poor performance of two-sided conditional t-tests found in Andrews, Moreira, and Stock (2007). These tests have bad power because the conditional null distributions of t-statistics are asymmetric when instruments are weak. Taking this asymmetry into account, we propose two-sided tests based on t-statistics. These novel tests are approximately unbiased and can perform as well as the conditional likelihood ratio (CLR) test. The second and third chapters are interested in maxmin and minimax regret tests for broader hypothesis testing problems. In the second chapter, we present maxmin and minimax regret tests satisfying more general restrictions than the alpha-level and the power control over all alternative hypothesis constraints. More general restrictions enable us to eliminate trivial known tests and obtain tests with desirable properties, such as unbiasedness, local unbiasedness and similarity. In sequence, we prove that both tests always exist and under suficient assumptions, they are Bayes tests with priors that are solutions of an optimization problem, the dual problem. In the last part of the second chapter, we consider testing problems that are invariant to some group of transformations. Under the invariance of the hypothesis testing, the Hunt-Stein Theorem proves that the search for maxmin and minimax regret tests can be restricted to invariant tests. We prove that the Hunt-Stein Theorem still holds under the general constraints proposed. In the last chapter we develop a numerical method to implement maxmin and minimax regret tests proposed in the second chapter. The parametric space is discretized in order to obtain testing problems with a finite number of restrictions. We prove that, as the discretization turns finer, the maxmin and the minimax regret tests satisfying the finite number of restrictions have the same alternative power of the maxmin and minimax regret tests satisfying the general constraints. Hence, we can numerically implement tests for a finite number of restrictions as an approximation for the tests satisfying the general constraints. The results in the second and third chapters extend and complement the maxmin and minimax regret literature interested in characterizing and implementing both tests.
Esta tese contém três capítulos. O primeiro capítulo considera testes de hipóteses para o coeficiente de regressão da variável endógena em um modelo de variáveis instrumentais. O foco é em testes-t condicionais para hipóteses unilaterais. Trabalhos teóricos e numéricos mostram que os testes-t condicionais centrados nos estimadores de 2SLS e Fuller performam bem mesmo quando os instrumentos são fracamente correlacionados com a variável endógena. Quando a estatística F populacional é menor que dois, o poder é razoavelmente próximo do poder envoltório para testes que são invariantes a transformações que rotacionam os instrumentos (similares ou não similares). Este resultado é surpreendente considerando a baixa performance dos testes-t condicionais para hipóteses bilaterais apresentado em Andrews, Moreira, and Stock (2007). Estes testes possuem baixo poder porque as distribuições das estatísticas-t na hipótese nula são assimétricas quando os instrumentos são fracos. Explorando tal assimetria, nós propomos testes para hipóteses bilaterais baseados em estatísticas-t. Estes testes são aproximadamente não viesados e podem performar tão bem quanto o teste de razão de máxima verossimilhança condicional. No segundo e no terceiro capítulos, nosso interesse é em testes do tipo maxmin e minimax regret para testes de hipóteses mais gerais. No segundo capítulo, nós apresentamos testes maxmin e minimax regret que satisfazem restrições mais gerais que as restrições de tamanho e de controle sobre todo o poder na hipótese alternativa. Restrições mais gerais nos possibilitam eliminar testes triviais e obter testes com propriedades desejáveis, como por exemplo não viés, não viés local e similaridade. Na sequência, nós provamos que ambos os testes existem e, sob condições suficientes, eles são testes Bayesianos com priors que são solução de um problema de otimização, o problema dual. Na última parte do segundo capítulo, nós consideramos testes de hipóteses que são invariantes à algum grupo de transformações. Sob invariância, o Teorema de Hunt-Stein implica que a busca por testes maxmin e minimax regret pode ser restrita a testes invariantes. Nós provamos que o Teorema de Hunt-Stein continua válido sob as restrições gerais propostas. No último capítulo, nós desenvolvemos um procedimento numérico para implementar os testes maxmin e minimax regret propostos no segundo capítulo. O espaço paramétrico é discretizado com o objetivo de obter testes de hipóteses com um número finito de pontos. Nós provamos que, ao considerarmos partições mais finas, os testes maxmin e minimax regret que satisfazem um número finito de pontos possuem o mesmo poder na hipótese alternativa que os testes maxmin e minimax regret que satisfazem as restrições gerais. Portanto, nós podemos implementar numericamente os testes que satisfazem um número finito de pontos como aproximação aos testes que satisfazem as restrições gerais.

Texto completoL'interesse iniziale di questo lavoro era testare l'effetto di un generico trattamento applicato a superfici tridimensionali. L'analisi di superfici tridimensionali presenta diversi problemi di varia natura. Innanzi tutto, ai dati rilevati sulle superfici per mezzo di scansioni laser non sono direttamente applicabili test statistici per almeno due motivi: il numero di punti rilevati non èlo stesso per tutti i soggetti, i punti non sono sincronizzati nel senso che punti riferiti a soggetti diversi, ma aventi la stessa posizione nella sequenza digitale, possono essere riferiti ad aree diverse della superficie. Questo problema è stato risolto utilizzando Funzioni a Base Radiale che forniscono dei coefficienti a cui è possibile applicare direttamente le procedure statistiche. Il problema è complicato dal fatto che il trattamento può generare, per alcuni coefficienti, degli effetti positivi su alcuni soggetti e negativi su altri e inoltre il numero dei coefficienti fornito dalla rappresentazione è notevolmente superiore al numero delle osservazioni. Per risolvere il primo di questi problemi è nato il multi-sided test. Il suo sviluppo in ambiente non parametrico ha contribuito a risolvere il secondo problema. Questo test è applicabile nelle situazioni in cui l'effetto di un trattamento può essere positivo su alcuni individui e negativo sugli altri. Tale situazione è sostanzialmente diversa da quella considerata nei tradizionali test bilaterali nei quali si assume che solo una delle due alternative può essere attiva, non entrambe. Il test multi-sided considera attive congiuntamente le due direzioni anche se in soggetti diversi. Al fine di affrontare questa situazione atipica, si possono applicare prima due ``goodness-of-fit'' tests, uno per gli effetti positivi e l'altro per quelli negativi e procedere poi con la loro combinazione non parametrica per via permutazione. Nelle situazioni in cui il numero di variabili è maggiore del numero di osservazioni, come nell'analisi di superfici, è conveniente utilizzare i test di permutazione poiché la potenza del test globale che si ottiene dalla combinazione dei test parziali, fatte salve alcune condizioni, aumenta monotonicamente al crescere della noncentralità. Infine, con opportune tecniche di correzione per la molteplicità è possibile identificare zone delle superfici maggiormente interessate dal trattamento.

This dissertation deals with the problem of making inference when there is weak identification in models of instrumental variables regression. More specifically we are interested in one-sided hypothesis testing for the coefficient of the endogenous variable when the instruments are weak. The focus is on the conditional tests based on likelihood ratio, score and Wald statistics. Theoretical and numerical work shows that the conditional t-test based on the two-stage least square (2SLS) estimator performs well even when instruments are weakly correlated with the endogenous variable. The conditional approach correct uniformly its size and when the population F-statistic is as small as two, its power is near the power envelopes for similar and non-similar tests. This finding is surprising considering the bad performance of the two-sided conditional t-tests found in Andrews, Moreira and Stock (2007). Given this counter intuitive result, we propose novel two-sided t-tests which are approximately unbiased and can perform as well as the conditional likelihood ratio (CLR) test of Moreira (2003).
Esta dissertação trata do problema de inferência na presença de identificação fraca em modelos de regresso com variáveis instrumentais. Mais especificamente em testes de hipóteses com relação ao parâmetro da variável endógena quando os instrumentos são fracos. O principal foco é nos testes condicionais unilaterais baseados nas estatísticas de razão de máxima verossimilhança, score e Wald. Resultados teóricos e numéricos mostram que o teste t condicional unilateral baseado no estimador de mínimos quadrados em dois estágios tem uma boa performance mesmo na presença de instrumentos fracamente correlacionados com a variável endógena. A abordagem condicional corrige uniformemente o tamanho do teste t e quando a estatística F populacional é tão pequena quanto dois, o poder do teste é próximo ao power envelope tanto de testes similares quanto de não similares. Tal resultado é surpreendente visto a má performance dos testes t’s condicionais bilaterais relatada em (6, Andrews, Moreira and Stock (2007)). Dado esse resultado aparentemente contra intuitivo, apresentamos novos testes t’s condicionals bilaterais que são aproximadamente não viesados e performam, em alguns casos, tão bem quanto o teste condicional baseado na estatística de razão de verossimilhança de ( 19 , Moreira (2003)).

Texto completoThis current paper is a testing study for seasonality in time linear series. The text is the result of an extensive search covering several articles and books related to this subject. Initially, a test of unit roots corresponding to seasonal frequencies in quarterly data is presented. This test is called procedure HEGY and it allows the unit roots to be tested in some isolated seasonal frequencies, without assuming that the unit roots are present at all seasonal frequencies. Then, the extension of this test to monthly data is analyzed and a test that combines the most powerful procedure is presented quarterly and monthly. Atypical observations and errors of measurement are studied to evaluate the effects that they can cause on the behavior of the unit root tests and to present a test that includes the correction of this difference. Finally, we examined the asymptotic robustness procedure HEGY in the presence of structural breaks (finite magnitude of change in seasonal average) and a more powerful test that incorporates a structural break is introduced. In order to illustrate and complement the presented theoretical analysis, some applications in real time series are developed. The data were obtained from the Instituto Brasileiro de Geografia e Estatística (IBGE) and the R software was used for the analysis.

Texto completoL'usure des composants ferriques dans les procédés minéralurgiques et un sujet bien étudié. Le laboratoire « Comminution Dynamics » a McGill à crée un modèle nommé « Total Media Wear Model » pour prédire le temps de l'avance nécessaire avant lequel il faudra remplacer les blindages et boulettes. Cette modèle comprend des simulations informatiques et des tests de laboratoire. Une autre mesure utilisée par les contremaitres et operateurs c'est le « Bond Work Index ». L'index donne une valeur approximative pour prédire la consommation d'énergie des moulins. Un test du style « Bond » exige beaucoup d'effort, et temps. Récemment, il a été suggérer qu'on pouvait obtenir des valeurs pour le « Bond Work Index » en utilisant un procédé modifié pour un des tests du « Total Media Wear Model ». Différentes nuances d'acier on été testé avec des niveaux d'énergie variées et sous des conditions sec et humide. Les résultats on démontré que les tests sec/humides n'était pas nécessairement équivalent, de plus, un changement dans la distribution granulométrique s'est produit entre la charge et le produit. Et finalement, l'analyse des données suggère qu'il y a une relation entre la valeur calculée de « Work Index » et l'énergie introduit dans la système. Ces résultats confirment les croyances qu'on pourra déterminer la valeur de « Bond Work Index » en même temps que les données du « Total Media Wear Model ». Cependant, il faudra des tests supplémentaires pour plusieurs types de minéraux. Cela pourra crée une base de données avec lequel des facteurs de corrélations pourront être déterminer.

Texto completoLa construction de modèles d'asymétrie est un sujet de recherche qui a connu un grand développement ces dernières années, et l'obtention des tests optimaux (pour trois modèles différents) est une étape essentielle en vue de leur mise en application.
Notre approche est fondée sur la théorie de Le Cam d'une part, pour obtenir les propriétés de normalité asymptotique, bases de la construction des tests paramétriques optimaux, et la théorie de Hajek d'autre part, qui, via un principe d'invariance permet d'obtenir les procédures non-paramétriques.
Nous considérons dans ce travail deux classes de distributions univariées asymétriques, l'une fondée sur un développement d'Edgeworth (décrit dans le Chapitre 1), et l'autre construite en utilisant un paramètre d'échelle différent pour les valeurs positives et négatives (le modèle de Fechner, décrit dans le Chapitre 2).
Le modèle d'asymétrie elliptique étudié dans le dernier chapitre est une généralisation multivariée du modèle du Chapitre 2.
Pour chacun de ces modèles, nous proposons de tester l'hypothèse de symétrie par rapport à un centre fixé, puis par rapport à un centre non spécifié.
Après avoir décrit le modèle pour lequel nous construisons les procédures optimales, nous obtenons la propriété de normalité locale asymptotique. A partir de ce résultat, nous sommes capable de construire les tests paramétriques localement et asymptotiquement optimaux. Ces tests ne sont toutefois valides que si la densité sous-jacente f est correctement spécifiée. Ils ont donc le mérite de déterminer les bornes d'efficacité paramétrique, mais sont difficilement applicables.
Nous adaptons donc ces tests afin de pouvoir tester les hypothèses de symétrie par rapport à un centre fixé ou non, lorsque la densité sous-jacente est considérée comme un paramètre de nuisance.
Les tests que nous obtenons restent localement et asymptotiquement optimaux sous f, mais restent valides sous une large classe de densités.
A partir des propriétés d'invariance du sous-modèle identifié par l'hypothèse nulle, nous obtenons les tests de rangs signés localement et asymptotiquement optimaux sous f, et valide sous une vaste classe de densité. Nous présentons en particulier, les tests fondés sur les scores normaux (ou tests de van der Waerden), qui sont optimaux sous des hypothèses Gaussiennes, tout en étant valides si cette hypothèse n'est pas vérifiée.
Afin de comparer les performances des tests paramétriques et non paramétriques présentés, nous calculons les efficacités asymptotiques relatives des tests non paramétriques par rapport aux tests pseudo-Gaussiens, sous une vaste classe de densités non-Gaussiennes, et nous proposons quelques simulations.

Texto completoMATS (Mesospheric Airglow/Aerosol Tomography and Spectroscopy) är en satellit som kommer attskjutas upp i 2019. Satelliten ska flyga i en låg omloppsbana och avbilda nattlysande moln och syreluftsken (airglow). Satelliten har CCD detektorer för att ta bilder av dessa fenomen i mesosfären.Sensorernas signaler behöver behandlas av en analog kedja innan de når ADC. Satelliter på bana ochderas komponenter kan påverkas av joniserande strålning från rymden.Elektronikenheter påverkas i en joniseringsprocess, som stör deras funktionalitet och prestanda.Tester måste göras över MATS komponenter för att garantera att överföringen av signalerna intepåverkas av strålningen och satelliten kan bibehålla sin prestanda. Syftet med detta arbete är attförklara de tester som utförts för att analysera de olika MATS-komponenterna vid liknandestrålningsförhållanden som det verkliga uppdraget och att hitta de mest lämpliga ersättningar ifall deursprungliga komponenterna visar sig inte vara lämpliga.
