This makes a lot of sense to me, because the need for it used to bite me a lot. As Austin implies, you need to -reshape- (or -stack-) to get official Stata commands to work here. That's the bad news. But -tabm- (in the package on SSC -tab_chi-) does it for you. That's the good news. Use -ssc inst tab_chi- to download. Stata 7 is required.
