Retrieves the R2 value from an H2O model. Will return R^2 for GLM Models. If "train", "valid", and "xval" parameters are FALSE (default), then the training R2 value is returned. If more than one parameter is set to TRUE, then a named vector of R2s are returned, where the names are "train", "valid" or "xval".
h2o.r2(object, train = FALSE, valid = FALSE, xval = FALSE)
object | An H2OModel object. |
---|---|
train | Retrieve the training R2 |
valid | Retrieve the validation set R2 if a validation set was passed in during model build time. |
xval | Retrieve the cross-validation R2 |
