These are not intended for use by users. calcL calculates the loss function of a model given a formatted Data object and a vector of coefficients beta. formatData formats the user-supplied data in the form required internally; formatPar does the same with control parameters. criteria.grpreg calculates the AIC, BIC, and GCV information criteria. unstandardize returns standardized coefficients to their original scale.
