Hello All

Thanks to Kit Baum, there is now a new package -pcontract- available for download on SSC. In Stata, type -ssc desc pcontract- to find out more.

-pcontract- is an extended version of -contract- which also generates percentages and, optionally, cumulative frequencies and percentages. It is described as below on my website.

Best wishes


package pcontract from

pcontract: Make a data set of frequencies and percentages

pcontract is an extended version of contract. It replaces the dataset in
memory with a new dataset consisting of all combinations of values of a list
of variables that exist in the existing data set and new variables containing
the frequency and percentage of each combination, and, optionally, the
cumulative frequency and percentage of each combination.
