grpregOverlap
grpregOverlap
fits the regularization paths of linear, logistic, Poisson,
or Cox models with overlapping grouped covariates based on the latent group lasso
approach (Jacob et al., 2009). Latent group MCP/SCAD as well as bi-level
selection methods, namely the group exponential lasso(Breheny, 2015) and the
composite MCP (Huang et al., 2012) are also available. This package serves as
an extension of R package grpreg
(by Dr. Patrick Breheny patrick-breheny@uiowa.edu)
for grouped variable selection involving overlaps between groups.
