Makes predictions from a shrunken GBM model.

shrink.gbm.pred(object, newdata, n.trees, lambda = rep(1,
  length(object$var.names)), ...)

Arguments

object

a gbm.object

newdata

dataset for predictions

n.trees

the number of trees to use

lambda

a vector with length equal to the number of variables containing the shrinkage parameter for each variable

...

other parameters (ignored)

Value

A vector with length equal to the number of observations in newdata containing the predictions

Warning

This function is experimental
