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

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 |
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
).
