h2o.residual_deviance: Retrieve the residual deviance

In h2o: R Interface for the 'H2O' Scalable Machine Learning Platform

Retrieve the residual deviance

Description

If "train", "valid", and "xval" parameters are FALSE (default), then the training residual deviance value is returned. If more than one parameter is set to TRUE, then a named vector of residual deviances are returned, where the names are "train", "valid" or "xval".

Usage

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

Arguments

object	An H2OModel or H2OModelMetrics
train	Retrieve the training residual deviance
valid	Retrieve the validation residual deviance
xval	Retrieve the cross-validation residual deviance

Examples

## Not run: 
library(h2o)
h2o.init()

prostate_path <- system.file("extdata", "prostate.csv", package = "h2o")
prostate <- h2o.importFile(prostate_path)
prostate[, 2] <- as.factor(prostate[, 2])
prostate_glm <- h2o.glm(y = "CAPSULE", x = c("AGE", "RACE", "PSA", "DCAPS"), 
                        training_frame = prostate, family = "binomial", 
                        nfolds = 0, alpha = 0.5, lambda_search = FALSE)
h2o.residual_deviance(prostate_glm, train = TRUE)
