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