Data Shared Neighbourhood Selection for multi-condition network inference
Blanche Francheterre, Ruben Colindres Zuehlke, Vivian Viallon +2
External stresses may affect both the circulating levels of specific biomarkers and disturb the correlation structures across molecular entities. The contribution of both types of…
On the estimation of inclusion probabilities for weighted analyses of nested case control studies
Tomeu López-Nieto-Veitch, Rossella De Sabbata, Ryung Kim +3
Nested case-control (NCC) studies are a widely adopted design in epidemiology to investigate exposure-disease relationships. This paper examines weighted analyses in NCC studies, f…
Optimal transport for automatic alignment of untargeted metabolomic data
Marie Breeur, George Stepaniants, Pekka Keski-Rahkonen +2
Untargeted metabolomic profiling through liquid chromatography-mass spectrometry (LC-MS) measures a vast array of metabolites within biospecimens, advancing drug development, disea…
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…
