Re-fitting Models with New Weights
Generic function for re-fitting a model object using the same observations but different weights.
reweight(object, weights, ...)
object |
a fitted model object. |
weights |
a vector of weights. |
... |
arguments passed to methods. |
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.
The re-weighted fitted model object.
## 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)
