On the use of cross-validation for the calibration of the adaptive lasso
Ballout Nadim, Etievant Lola, Viallon Vivian
The adaptive lasso refers to a class of methods that use weighted versions of the -norm penalty, with weights derived from an initial estimate of the parameter vector to be es…
On some limitations of probabilistic models for dimension-reduction: Illustration in the case of probabilistic formulations of partial least squares
Lola Etievant, Vivian Viallon
Partial Least Squares (PLS) refer to a class of dimension-reduction techniques aiming at the identification of two sets of components with maximal covariance, to model the relation…
Sparse estimation for case-control studies with multiple subtypes of cases
Nadim Ballout, Cedric Garcia, Vivian Viallon
The analysis of case-control studies with several subtypes of cases is increasingly common, e.g. in cancer epidemiology. For matched designs, we show that a natural strategy is bas…
Causal inference under over-simplified longitudinal causal models
Lola Etievant, Vivian Viallon
Many causal models of interest in epidemiology involve longitudinal exposures, confounders and mediators. However, repeated measurements are not always available or used in practic…
A Bayesian information criterion for singular models
Mathias Drton, Martyn Plummer
We consider approximate Bayesian model choice for model selection problems that involve models whose Fisher-information matrices may fail to be invertible along other competing sub…
