Iterative proportional fitting in r
Web26 jan. 2024 · Some studies have found that a first stage of adjustment using matching or propensity weighting followed by a second stage of adjustment using raking can be more effective in reducing bias than any single method applied on its own. 16 Neither matching nor propensity weighting will force the sample to exactly match the population on all … Web26 jan. 2024 · For public opinion surveys, the most prevalent method for weighting is iterative proportional fitting, more commonly referred to as raking. With raking, a …
