| Mar 11, 2011 at 19:31 | comment | added | Gottfried Helms | @Or zuk: that's exactly how -for instance- SPSS handles that weighting; it's implemented as a standard option in each statistical procedure. Actually I know its use of some studies, where the parameters of a distorted sample were compared with that of a population, where the underrepresentated subsamples are weighted higher and the overrepresented samples were weighted lower such that each subsample/group has the same relative size as in the population. The algorithms of SPSS are openly availabe as far as I recall (www.spss.com) but may be you have to go over the new owner instead (IBM) | |
