R: Predictions from a shrunked GBM

shrink.gbm.pred {gbm} | R Documentation

## Predictions from a shrunked GBM

### Description

Makes predictions from a shrunken GBM model.

### Usage

    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
