Generic function for refitting a models on various subsets or reweighted data sets.
refit(object, …)an object.
arguments passed to methods.
refit is a new generic function for refitting a certain
model object on multiple versions of a data set (and is hence
different from update). Applications are partitioned/segmented
models where the same type of model should be refitted on each
sub-sample or partition. See fxregimes
for such an example. Another application would be reweighted
models such as in mixture models.
The generic is similar to the one provided in modeltools (and should fulfill the same purpose). To avoid dependence on this package, it is also provided here.
