If "train", "valid", and "xval" parameters are FALSE (default), then the training null degrees of freedom value is returned. If more than one parameter is set to TRUE, then a named vector of null degrees of freedom are returned, where the names are "train", "valid" or "xval".
h2o.null_dof(object, train = FALSE, valid = FALSE, xval = FALSE)
Retrieve the training null degrees of freedom
Retrieve the validation null degrees of freedom
Retrieve the cross-validation null degrees of freedom
