Retrieve the null degrees of freedom 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
