Tabulation of multiple response sets, revisited

At the first German Stata Users Group meeting, Hildegard Schaeper raised the issue of tabulating multiple response sets with Stata. Hildegard presented two of her own programs to deal with multiple responses and identified a number of remaining problems. In my contribution, I will re-address the issue and present a revised and considerably extended module to compute one- and two-way tables of multiple responses. The new program handles dichotomously or polytomously held response sets, calculates absolute frequencies as well as frequencies relative to responses and/or cases, supports string variables, appropriately labels rows and columns, allows complex case selection and specification of a list or range of valid responses, offers significance tests for two-way tables, and optionally saves response indicator variables. Tables are neatly formatted and split into pieces if too wide to fit the screen. The program is byable and weights are allowed.
