Generic function for re-fitting a model object using the same observations but different weights.
reweight(object, weights, …)
a fitted model object.
a vector of weights.
arguments passed to methods.
The re-weighted fitted model object.
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.
# NOT RUN {
## 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)
# }
