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…
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…
Which practical interventions does the do-operator refer to in causal inference? Illustration on the example of obesity and cancer
Lola Etievant, Vivian Viallon
For exposures like obesity, no precise and unambiguous definition exists for the hypothetical intervention . This has raised concerns about the relevance of causal…
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…
