Web8 de jul. de 2024 · Here, also the logistic regression model in the high-dimensional case is treated robustly. The procedures are implemented in the R package enetLTS (Kurnaz, Hoffmann, & Filzmoser, 2024a). IFs in the context of many penalized regression estimators as discussed above are considered in Öllerer, Croux, and Alfons . Web4 de dez. de 2006 · We describe a method based on l1-regularized logistic regression, in which the neighborhood of any given node is estimated by performing logistic regression subject to an l-constraint. Our framework applies to the high-dimensional setting, in which both the number of nodes p and maximum neighborhood sizes d are allowed to grow as …

A popular scalable alternative is variational Bayes (VB), which approximates the posterior by solving an optimization problem. chip shop malpas
