R: Re-fitting Models with New Weights

reweight {party} | R Documentation

## Re-fitting Models with New Weights

### Description

Generic function for re-fitting a model object using the same observations but different weights.

### Usage

    reweight(object, weights, ...)

### Arguments

`object` | a fitted model object.
`weights` | a vector of weights.
`...` | arguments passed to methods.

### Details

The method is not unsimilar in spirit to `update`, but much more narrowly focused. It should return an updated fitted model derived from re-fitting the model on the same observations but using different weights.

### Value

The re-weighted fitted model object.

### See Also

`update`

### Examples

      ## fit cars regression
      mf <- dpp(linearModel, dist ~ speed, data = cars)
      fm <- fit(linearModel, mf)
      fm

      ## re-fit, excluding the last 4 observations
      ww <- c(rep(1, 46), rep(0, 4))
      reweight(fm, ww)
