infcrit.dof: Information criteria

Description

This function computes information criteria for existing plsR model using Degrees of Freedom estimation.

Usage

infcrit.dof(modplsR, naive = FALSE)

Arguments

modplsR

A plsR model i.e. an object returned by one of the functions plsR, plsRmodel.default, plsRmodel.formula, PLS_lm or PLS_lm_formula.

naive

A boolean.

Value

matrix

AIC, BIC and gmdl values or NULL.

Details

If naive=FALSE returns AIC, BIC and gmdl values for estimated and naive degrees of freedom. If naive=TRUE returns NULL.
