h2o.giniCoef: Retrieve the GINI Coefficcient

Description

Retrieves the GINI coefficient from an . If "train", "valid", and "xval" parameters are FALSE (default), then the training GINIvalue is returned. If more than one parameter is set to TRUE, then a named vector of GINIs are returned, where the names are "train", "valid" or "xval".

Usage

h2o.giniCoef(object, train = FALSE, valid = FALSE, xval = FALSE)

Arguments

object

an object.

train

Retrieve the training GINI Coefficcient

valid

Retrieve the validation GINI Coefficcient

xval

Retrieve the cross-validation GINI Coefficcient
