Pluntz, Matthieu. "Sélection de variables en grande dimension par le Lasso et tests statistiques - application à la pharmacovigilance." Electronic Thesis or Diss., université Paris-Saclay, 2024. http://www.theses.fr/2024UPASR002.
Variable selection in high-dimensional regressions is a classic problem in health data analysis. It aims to identify a limited number of factors associated with a given health event among a large number of candidate variables such as genetic factors or environmental or drug exposures.The Lasso regression (Tibshirani, 1996) provides a series of sparse models where variables appear one after another depending on the regularization parameter's value. It requires a procedure for choosing this parameter and thus the associated model. In this thesis, we propose procedures for selecting one of the models of the Lasso path, which belong to or are inspired by the statistical testing paradigm. Thus, we aim to control the risk of selecting at least one false positive (Family-Wise Error Rate, FWER) unlike most existing post-processing methods of the Lasso, which accept false positives more easily.Our first proposal is a generalization of the Akaike Information Criterion (AIC) which we call the Extended AIC (EAIC). We penalize the log-likelihood of the model under consideration by its number of parameters weighted by a function of the total number of candidate variables and the targeted level of FWER but not the number of observations. We obtain this function by observing the relationship between comparing the information criteria of nested sub-models of a high-dimensional regression, and performing multiple likelihood ratio test, about which we prove an asymptotic property.Our second proposal is a test of the significance of a variable appearing on the Lasso path. Its null hypothesis depends on a set A of already selected variables and states that it contains all the active variables. As the test statistic, we aim to use the regularization parameter value from which a first variable outside A is selected by Lasso. This choice faces the fact that the null hypothesis is not specific enough to define the distribution of this statistic and thus its p-value. We solve this by replacing the statistic with its conditional p-value, which we define conditional on the non-penalized estimated coefficients of the model restricted to A. We estimate the conditional p-value with an algorithm that we call simulation-calibration, where we simulate outcome vectors and then calibrate them on the observed outcome‘s estimated coefficients. We adapt the calibration heuristically to the case of generalized linear models (binary and Poisson) in which it turns into an iterative and stochastic procedure. We prove that using our test controls the risk of selecting a false positive in linear models, both when the null hypothesis is verified and, under a correlation condition, when the set A does not contain all active variables.We evaluate the performance of both procedures through extensive simulation studies, which cover both the potential selection of a variable under the null hypothesis (or its equivalent for EAIC) and on the overall model selection procedure. We observe that our proposals compare well to their closest existing counterparts, the BIC and its extended versions for the EAIC, and Lockhart et al.'s (2014) covariance test for the simulation-calibration test. We also illustrate both procedures in the detection of exposures associated with drug-induced liver injuries (DILI) in the French national pharmacovigilance database (BNPV) by measuring their performance using the DILIrank reference set of known associations
