In jeremyrcoyle/sl3: Pipelines for Machine Learning and Super Learning

Description Format Value Parameters References See Also Examples

This learner implements Bayesian Additive Regression Trees via bartMachine (described in \insertCitebartMachine;textualsl3) and the function bartMachine.

An R6Class object inheriting from Lrnr_base.

A learner object inheriting from Lrnr_base with methods for training and prediction. For a full list of learner functionality, see the complete documentation of Lrnr_base.

...: Parameters passed to bartMachine. See it's documentation for details.
