h2o.giniCoef: Retrieve the GINI Coefficcient

Description

Retrieves the GINI coefficient from an H2OBinomialMetrics.

Usage

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

Arguments

object

an H2OBinomialMetrics object.

valid

TRUE to extract the metric from validation set metrics; otherwise, training is assumed

...

extra arguments to be passed if `object` is of type H2OModel (e.g. train=TRUE)

hex <- h2o.uploadFile(prosPath)

hex[,2] <- as.factor(hex[,2])
model <- h2o.gbm(x = 3:9, y = 2, training_frame = hex, distribution = "bernoulli")
perf <- h2o.performance(model, hex)
