h2o (version 3.10.3.6)

h2o.r2: Retrieve the R2 value

Description

Retrieves the R2 value from an H2O model. Will return R^2 for GLM Models and will return NaN otherwise. 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 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

library(h2o)

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

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

h2o.r2(m)
