Multiple Responses/Dichotomies - A Final Comment

When preparing complex crosstabulation tables with multiple responses/dichotomies, it is sometimes difficult (in our experience) to "keep track" of exactly how the cases in the file are counted. The best way to verify that one understands the way in which the respective tables are constructed is to crosstabulate some simple example data, and then to trace how each case is counted. The Crosstabulation example section employs this method to illustrate how data are counted for tables involving multiple response variables and multiple dichotomies.
