Group Penalised Logistic Regression
Several Lasso packages in CRAN. Needed one with 1) Group penalties 2) Support for sparse Matrices 3) Offset terms!
None existed that fullfilled all three, so wrote this.
We use local coordinate descent (LCD), as described in the reference.
Main function is glbin_lcd_c
, sparse version glbin_lcd_c_sparse
.
