Retrieve the log likelihood value

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".

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

# NOT RUN {
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)
# }
