predict.SuperLearner {SuperLearner}

Predict method for SuperLearner object

Description

Obtains predictions on a new data set from a SuperLearner fit. May require the original data if one of the library algorithms uses the original data in its predict method.

Usage

## S3 method for class 'SuperLearner'
predict(object, newdata, X = NULL, Y = NULL,
  onlySL = FALSE, ...)

Arguments

object

Fitted object from SuperLearner

newdata

New X values for prediction

X

Original data set used to fit object, if needed by fit object.

Y

Original outcome used to fit object, if needed by fit object.

onlySL

Logical. If TRUE, only compute predictions for algorithms with non-zero coefficients in the super learner object. Default is FALSE (computes predictions for all algorithms in library).

...

Additional arguments passed to the predict.SL.* functions

Details

If newdata is omitted the predicted values from object are returned. Each algorithm in the Super Learner library needs to have a corresponding prediction function with the “predict.” prefixed onto the algorithm name (e.g. predict.SL.glm for SL.glm).

Value

pred

Predicted values from Super Learner fit

library.predict

Predicted values for each algorithm in library
