Internal grpreg functions
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)
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.
