mpath (version 0.1-20)

methods: Methods for mpath Objects

Description

Methods for models fitted by coordinate descent algorithms.

Usage

## S3 method for class 'glmreg':
AIC(object, ..., k)
## S3 method for class 'zipath':
AIC(object, ..., k)
## S3 method for class 'glmreg':
BIC(object, ...)
## S3 method for class 'zipath':
BIC(object, ...)

Arguments

object

objects of class glmreg or zipath.

...

additional arguments passed to callies.

k

numeric, the penalty per parameter to be used; the default k = 2 is the classical AIC. k has been hard coded in the function and there is no impact to the value of AIC if k is chang
