XCONTRACT: Stata module to make a data set of frequencies and percents on disk or in memory

Statistical Software Components from Boston College Department of Economics

Abstract: xcontract is an extended version of contract. It creates an output data set with 1 observation per combination of values of the variables in varlist and data on the frequencies and percents of those combinations of values in the existing data set, and, optionally, the cumulative frequencies and percents of those combinations. If the by() option is used, then the output data set has one observation per combination of values of the varlist variables per by-group, and percents are calculated within each by-group. The output data set created by xcontract may be listed to the Stata log, or saved to a data frame, or saved to a disk file, or written to the memory (overwriting any pre-existing data set).
