R Documentation

Use SuperLearner Wrappers, Screeners, and Methods, in sl3

Description

These learners provide an interface to the wrapper functions, screening algorithms, and combination methods provided by the SuperLearner package. These components add support for a range of algorithms not currently implemented natively in sl3.

Lrnr_pkg_SuperLearner - Interface for SuperLearner wrapper functions. Use SuperLearner::listWrappers("SL") for a list.

Use SuperLearner::listWrappers("method") for a list of options.

Use SuperLearner::listWrappers("screen") for a list of options.

Format

R6Class object.

Value

Learner object with methods for training and prediction. See Lrnr_base for documentation on learners.

Parameters

SL_wrapper: The wrapper function to use.
...: Currently not used.

Common Parameters

Individual learners have their own sets of parameters. Below is a list of shared parameters, implemented by Lrnr_base, and shared by all learners.

covariates: A character vector of covariates. The learner will use this to subset the covariates for any specified task
outcome_type: A variable_type object used to control the outcome_type used by the learner. Overrides the task outcome_type if specified
...: All other parameters should be handled by the invidual learner classes. See the documentation for the learner class you're instantiating
