Texte intégralMeasurement's reliability refers to its reproducibility when it is randomly repeated on the same subject and is a key metrological property for each measurement validation. The two-way intra-class correlation coefficient of agreement (ICCa) is a statistical parameter used to quantify the inter-rater reliability of continuous (or ordinal qualitative) measurements. It constitute a central reliability index recommended by the regulatory agencies. Nevertheless, its estimators are biased and a lot of solutions have been tried facing to its confidence interval (CI) problem. The latest works indicate that no method works well with a hard-to-detect violation of normality and when the number of subjects OR raters is limited, which is rather the case in practice. Furthermore, no variance stabilizing transformation (VST) nor statistical comparative test are available for the ICCa. The aim of this thesis is therefore to contribute to the development of methods that remedy the lack of the inferential tools for the ICCa. At a first step, we propose new asymptotic methods for the ICCa confidence interval, the calculation of the needed sample size of subjects and raters, and a likelihood ratio test to compare two ICCa. Then, in a second work, we develop three VSTs, improving the properties of the confidence interval for inter-rater reliability studies of moderate sample size, and the synthesis of several ICCa in the context of meta-analyses. Finally, in a third work, dedicated resampling methods are proposed, in combination with the best VST, to improve the ICCa confidence interval performances in case of non-normality with small sample size. It is above all a work of biostatistical methodology, with simulation evaluations of the introduced methods, and applications to several real data sets from inter-rater reliability studies and meta-analyses

For cDNA microarray data, the variance of gene is usually not the same and depends on its mean. Durbin et al. (2002) and Inoue et al. (2004) established the one-color gene expression model and obtain the relationship between variance of gene and its mean. They then derive the variance-stabilizing transformation function to stabilize the variance of the genes. In this article, we consider the two-color design and use nonparametric regression approach to stabilize the variance of gene expression level. We first, by applying lowess method, find the relationship between variance and mean of gene expression from scatter plot of variance versus mean, then use exponential function to approximate the relationship between variance and mean in a small region. Simulation study and real data analysis show that the performance of the suggested method is comparable to the parametric variance stabilization approach when the variance function is known.

To define a likelihood we have to specify the form of distribution of the observations. However, to define a quasi- likelihood function we need only to specify the relationship between mean and variance of the distribution concerned. Quasi- likelihood can be used for estimation and it enlarges the scope of the analysis of data. For the data set which do not satisfy the assumptions of ordinary analysis, traditional transformations such as square root, logarithmic and angular transformation are used to achieve thenormality and stabilize the variances. This thesis investigates the possibility to use an alternative, that is, using a generalized linear models with some given variance functions. Also the similarities and differences between these two approaches were studied by numerical examples. We consider six numerical examples for illustrating the applications of quasi-likelihood functions and for comparing the two different approaches. First three data sets are of the form of one-way tables and second three data sets are of theform of two-way tables. For each data set, we compute two measures and for comparing the effectiveness in estimation and model fitting, res of these two approaches. In the generalized linear model considered, the link functions which playing the role of achieving the additivity have different forms from the traditional transformations. However, the results obtained from this study show that these two approaches are quite similar in effectiveness in estimation and model fitting. This kind of similarity suggests that both approaches might be equivalent and the equivalence might be proved mathematically.
