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)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.
