dglars-package: Differential geometric LARS (dgLARS) method for some generalized linear models

Description

This package implements the differential geometric extension of the least angle regression method (Efron et al., 2004) proposed in Augugliaro et al. (2013). Using this version of the package it is possible to compute the dgLARS solution curve for the logistic and Poisson regression models. The solution curve can be computed using two different algorithms, i.e., a predictor-corrector algorithm and a cyclic coordinate descent algorithm.
