A person's lipid profile is influenced by genetic variants and alcohol consumption, but the contribution of interactions between these exposures has not been studied. We therefore incorporated gene-alcohol interactions into a multiancestry genome-wide association study of levels of high-density lipoprotein cholesterol, low-density lipoprotein chole...

Meteorological ensemble members are a collection of scenarios for future weather issued by a meteorological center. Such ensembles nowadays form the main source of valuable information for probabilistic forecasting which aims at producing a predictive probability distribution of the quantity of interest instead of a single best guess point-wise est...

Using clinical data to model the medical decisions behind sequential treatment actions raises methodological challenges. Physicians often have access to many covariates that may be used when making sequential treatment decisions for individual patients. Statistical variable selection methods may help finding which of these variables are used for th...

Cette recherche est motivée par l'étude d'inondations côtières au moyen d'un grand simulateur numérique. Chaque appel au simulateur renvoie une image, correspondant à une carte de hauteur d'eau inondée, en fonction de paramètres d'entrée liés à la mer. L'objectif est de prévoir l'image correspondant à un nouveau jeu de paramètres. Dans ce contexte,...

Well-type re-entrant ionization chambers (IC) are used in radionuclide metrology for secondary measurements of radioactive sources. Generally this technique is used for solutions of gamma-emitting radionuclides, but was also extended to high-energy beta-emitting radionuclides like 90Y. In this case, the energy transfer to the gas is made through Br...

A new method for combining several initial estimators of the regression function is introduced. Instead of building a linear or convex optimized combination over a collection of basic estimators $r_1,\dots,r_M$, we use them as a collective indicator of the proximity between the training data and a test observation. This local distance approach is m...

Currently there is limited information to estimate accurate and reliable mangrove forest area in Cambodia. Previous estimates did not explicitly illustrate the spatial distribution of mangrove for the entire country however , according to Global Forest Resource Assessment 2010, Cambodia's mangrove area cover in 1990 and 2010 was calculated at 79,63...

Estimating and selecting risk factors with extremely low prevalences of exposure for a binary outcome is a challenge because classical standard techniques, markedly logistic regression, often fail to provide meaningful results in such settings. While penalized regression methods are widely used in high-dimensional settings, we were able to show the...
