h2o (version 3.44.0.3)

h2o.loglikelihood: Retrieve the log likelihood value

Description

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

Usage

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

Arguments

object

An H2OModel or H2OModelMetrics.

train

Retrieve the training log likelihood

valid

Retrieve the validation log likelihood

xval

Retrieve the cross-validation log likelihood

Examples

if (FALSE) {
library(h2o)
h2o.init()
prostate_path <- system.file("extdata", "prostate.csv", package = "h2o")
prostate <- h2o.uploadFile(path = prostate_path)
p_sid <- h2o.runif(prostate)
prostate_train <- prostate[p_sid > .2,]
prostate_glm <- h2o.glm(x = 3:7, y = 2, training_frame = prostate_train)
ll_basic <- h2o.loglikelihood(prostate_glm)
print(ll_basic)
