Retrieves the PR AUC table from an H2OMultinomialMetrics. If "train", "valid", and "xval" parameters are FALSE (default), then the training PR AUC table is returned. If more than one parameter is set to TRUE, then a named vector of PR AUC tables are returned, where the names are "train", "valid" or "xval".
h2o.multinomial_aucpr_table(object, train = FALSE, valid = FALSE, xval = FALSE)
An H2OMultinomialMetrics object.
Retrieve the training PR AUC table
Retrieve the validation PR AUC table
Retrieve the cross-validation PR AUC table
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.
