Full textOur line of investigation has developed in the field of the statistical applied to the finances. Our aim is to find and analyse new statistical models to adjust the financial data and new techniques to study the behavior of the tails. An application of this work is the study of operational risk. The banking business has changed deeply by the processes of liberalization, financial and technological innovation. This, has generated an evolution in the field of modeling the processes for the measurement and the quantification of the risk. The risk of loss has his origin in events that can not be attribute to market risk or to credit risk, it is resulting from inadequate or failed internal processes, people and systems or from external events. This definition includes legal risk but excludes strategic and reputacional risk. The most recent method for hedging the operational risk is the method of advanced measurement (AMA) that consists in modeling the aggregate distribution of losses (Loss Distribution Approach or LDA) that has been used successfully in the field of insurances. assuming that the severities are independent, and, that are independent of the frequency of the events, the methodology LDA requires modeling separately the frequency and the severity. The VaR is then calculated as the percentile of the aggregate distribution of losses for a level of probability 99;9%. In the Chapter one, we give an overview on heavy-tailed distributions. Historically, it have been used in the world of insurances, specifically the distributions subexponentials. In the last decade, this methodology has moved to the world of the finances. In the Chapter two, it is shown that the prices formation mechanism may explain some amount of non-normality. Assuming normality for bid and ask prices, the observed transaction prices may be a mixture of normal distributions or a mixture of left- right truncated normal distributions, the latter case being more likely. The statistical properties of the mixture of left-right truncated normal distri- butions are developed. It is proved that there is only one maximum for the likelihood function and the maximum is closely related to the coeficient of variation. Our results show that continuity at zero of this distribution can be avoided in statistical analysis. Empirical work suggests that in financial data non-normality is also produced for a large number of values close to the mean, here referred to as ïnliers". This could explain that the Laplace approximation is often a better approach than normal distribution for daily returns. The approach based in the modeling the distribution of severity by semi weighed distributions such as the lognormal distribution, the inverse gaussian and the mixture of normal provide robust estimates estables of the VaR. The approach based in the theory of extreme value that adjust the values over an determined threshold by the generalized Pareto distribution is of importance To obtain values estables of the measures of the risk. In the Chapter three, we provide precise arguments to explain the anomalous behavior of the likelihood surface when sampling from the generalized Pareto distribution for small or moderate samples. The behavior of the profile-likelihood function is characterized in terms of the empirical coefficient of variation. A suficient condition is given for global maximum of the likelihood function of the Pareto distribution to be at a finite point. In the Chapter four, we develop a previous and complementary methodology to the parametric studies to contrast the model from a point of empirical view. New methods to decide between polynomial or exponential tails are introduced. Is an alternative method to the classical methods ME-Plot and the Hill-Plot. The key idea is based on a characterization of the exponential distribution and uses the residual coefficient of variation as a random process. A graphical method, called a CV plot, is introduced to distinguish between exponential and polynomial tails. Moreover, new statistics introduced from a multivariate point of view allow for testing exponentiality using simultaneously several thresholds. The usefulness of our approach is clearly shown with the daily returns of exchange rates between the US dollar and the Japan yen. One of the difficulties of the distribution of generalized Pareto is that include bounded distributions, there lead a problems of convergence of the estimators. Besides the likelihood functions for small samples can not having solutions. Thus, we propose the TNP distribution that is the union of the normal truncated, the exponential distribution and the distribution of Pareto and is an alternative to the distribution GPD to modeling financial data.

Full textExtreme value theory (EVT) is the only statistical discipline that develops techniques and models to describe the unusual behavior instead of the usual one, the main objective of which is the quantile estimation corresponding to very extreme events. In many areas of application, a typical requirement is to estimate the value at risk (VaR), high enough to overcome the possibility that this is less than a given amount. The probability theory associated to the EVT is well-established thanks to the results of Fisher and Tippet (1923), Balkema and de Haan (1974), and Pickands (1975). Two main approaches were developed; the block maxima method and the method of the excesses over a threshold, the application of which presents difficulties in applying statistical tools, Diebold et al. (1998). The determination of the threshold from which the limit distribution can be used and its behavior are the main problems to deal with. To distinguish the general data from those which are under study, we will use the concept of tail, which refers to values that are above a sufficiently high value. For excesses over a threshold the distribution that characterizes the asymptotic behavior of the tail is the Generalized Pareto (GPD), its shape parameter, called extreme value index, classifies tails in heavy, exponential, and light. The application of the GPD model is extensively detailed in McNeil et al. (2005) and Embrechts et al. (1997), but there are limitations, for example, when there are no finite moments or the subjectivity that arises when graphical methods are used. The aim of this thesis is to present new tools for EVT, which can be used for the threshold selection and the extreme value index estimation and they solve some existing problems. Chapter 1 is a review of statistical theory for extreme values. The most used graphical methods are remembered, the mean excess plot and the Hill-plot, and the estimation methods available for GPD too. Finally, a new graphical method called CV plot, Castillo et al. (2014), and a recently appeared approach to heavy and exponential tails, Castillo et al. (2013), are presented. In Chapter 2 the fact that the coefficient of variation characterizes residual distributions, Gupta and Kirman (2000), is used to find the theoretical CV plot for some distributions and to apply the asymptotic theory to the case of GPD, provided by the existence of four finite moments. Thanks to a transformation, presented in Chapter 3, the CV-plot can be applied in any situation. Chapter 4 presents statistics that allow us to estimate the extreme value index, to contrast the hypothesis of GPD and they are used in an automated selection thresholds algorithm. This third point is a major breakthrough for the application of the method Peak over Threshold, which requires estimating the threshold from a graphical method and estimating the extreme value index through the maximum likelihood, Coles (2001), since researcher's subjectivity disappears when the threshold is estimated. Chapter 5 is dedicated to the study of 16 data sets in embedded systems. The CV plot and statistical Tm have been used, obtaining good results in most cases. In Chapter 6, we will again apply new tools to data on Danish fire insurance, McNeil (1997), and financial data analyzed in Gomes and Pestana (2007). Finally, Chapter 7 presents the conclusions of this work and the new lines of research.
