If "train", "valid", and "xval" parameters are FALSE (default), then the training null deviance value is returned. If more than one parameter is set to TRUE, then a named vector of null deviances are returned, where the names are "train", "valid" or "xval".
h2o.null_deviance(object, train = FALSE, valid = FALSE, xval = FALSE)
| object | An H2OModel or H2OModelMetrics |
|---|---|
| train | Retrieve the training null deviance |
| valid | Retrieve the validation null deviance |
| xval | Retrieve the cross-validation null deviance |
