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.
- this package now works for survival analysis (Cox model) by specifying "family = cox".
