Description

Internal grpreg functions

Usage

calcL(X,y,beta,family)
setupLambda(X,y,group,family,J,K,penalty,lambda.max,lambda.min,n.lambda,a,gamma)
criteria.grpreg(X,y,beta,family,method,df)
unstandardize(beta,meanx,normx)

Details

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. setupLambda creates an appropriate vector of regularization parameter values. criteria.grpreg calculates the AIC, BIC, and GCV information criteria. unstandardize returns standardized coefficients to their original scale.
