The -ipfweight- command performs an iterative proportional fitting algorithm to create survey sampling weights and contains some additional features not available in Nick Winter's -survwgt- command. See the description below.

TITLE 'IPFWEIGHT': module to create adjustment weights for surveys DESCRIPTION/AUTHOR(S) ipfweight performs a stepwise adjustment (known as iterative proportional fitting or raking) of survey sampling weights to achieve known population margins. The iterative process is repeated until the difference between the sample margins and the known population margins is smaller than a specified tolerance value or the specified maximum number of iterations is obtained. Additionally, thresholds for maximum and minimum weighting factors can be specified as well as a simple replacement of missing values.
