Internal grpreg functions

Description

Internal grpreg functions

Usage

setupLambda(X, y, group, family, penalty, alpha, lambda.min, log.lambda, nlambda,
group.multiplier) 
setupLambda.gBridge(X, y, group, family, alpha, lambda.min, lambda.max,
nlambda, gamma, group.multiplier) 
standardize(X)
unstandardize(b, center, scale)
orthogonalize(X, group)
unorthogonalize(b, XX, group, intercept = TRUE)

Details

These are not intended for use by users. setupLambda and setupLambda.gBridge create appropriate vectors of regularization parameter values. The functions of standardize, unstandardize, orthogonalize, and unorthogonalize are self-explanatory.
