Retrieve the log likelihood value — h2o.loglikelihood • h2o

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) { # \dontrun{
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)
} # }
