Retrieves the pr_auc value from an H2OBinomialMetrics. If "train", "valid", and "xval" parameters are FALSE (default), then the training pr_auc value is returned. If more than one parameter is set to TRUE, then a named vector of pr_aucs are returned, where the names are "train", "valid" or "xval".
h2o.pr_auc(object, train = FALSE, valid = FALSE, xval = FALSE)
object | An H2OBinomialMetrics object. |
---|---|
train | Retrieve the training pr_auc |
valid | Retrieve the validation pr_auc |
xval | Retrieve the cross-validation pr_auc |
h2o.giniCoef
for the Gini coefficient,
h2o.mse
for MSE, and h2o.metric
for the
various threshold metrics. See h2o.performance
for
creating H2OModelMetrics objects.
