predict.l1ce {lasso2}R Documentation

Predict Method for `l1ce' Objects

Description

Extracts the fitted values from a l1ce object and returns a matrix of predictions.

Usage

predict.l1ce(object, newdata, type=c("response"), se.fit = FALSE, ...)

Arguments

object a fitted l1ce object.
newdata a data frame containing the values at which predictions are required. This argument can be missing, in which case predictions are made at the same values used to compute the object. Only those predictors referred to in the right side of the formula in object need be present by name in newdata.
type currrently only "response".
se.fit logical indicating if standard errors should be returned as well. Not yet available.
... further potential arguments passed to methods.

Details

This function is a method for the generic function predict for class "l1ce". It can be invoked by calling predict for an object of the appropriate class, or directly by calling predict.l1ce regardless of the class of the object.

Value

a vector of predictions.

Warning

predict can produce incorrect predictions when the newdata argument is used if the formula in object involves transformations, such as poly(Age, 3) or sqrt(Age - min(Age)).
