Speaking Stata: Problems with tables, Part II
Abstract. Three user-written commands are reviewed as illustrations of different
approaches to tabulation problems, each one step beyond what is possible to
do directly through official Stata. tabcount is a wrapper for
tabdisp written to produce tables that show how often specified
values occur or specified conditions are satisfied so that, in particular,
tables may include explicit zeros whenever desired. makematrix is
designed for situations in which a table of results may be compiled by
populating a matrix. matrix list or list may then be used to
display the table. groups shows frequencies of combinations of values
using list. Users should find these commands to be helpful additions to the
toolkit. Programmers may be interested in examples of the wrapper approach,
calculating the values to be tabulated before passing them to a workhorse
display command. This is the second of two papers on this topic.
