Retrieve the R2 value — h2o.r2 • h2o

Retrieves the R2 value from an H2O model. Will return R^2 for GLM Models. If "train", "valid", and "xval" parameters are FALSE (default), then the training R2 value is returned. If more than one parameter is set to TRUE, then a named vector of R2s are returned, where the names are "train", "valid" or "xval".

Usage

h2o.r2(object, train = FALSE, valid = FALSE, xval = FALSE)

Arguments

object: An H2OModel object.
train: Retrieve the training R2
valid: Retrieve the validation set R2 if a validation set was passed in during model build time.
xval: Retrieve the cross-validation R2

Examples

if (FALSE) { # \dontrun{
library(h2o)

h <- h2o.init()
fr <- as.h2o(iris)

m <- h2o.glm(x = 2:5, y = 1, training_frame = fr)

h2o.r2(m)
} # }
