h2o.qini: Retrieve the default Qini value

Description

Retrieves the Qini value from an '>H2OBinomialUpliftMetrics. If "train" and "valid" parameters are FALSE (default), then the training Qini value is returned. If more than one parameter is set to TRUE, then a named vector of Qini values are returned, where the names are "train", "valid".

Usage

h2o.qini(object, train = FALSE, valid = FALSE)

Arguments

object

An '>H2OBinomialUpliftMetrics or

train

Retrieve the training Qini value

valid

Retrieve the validation Qini
