Re: st: Csgof does not count var categories with zero observations

[Nick Cox <njcoxstata@gmail.com>]

-csgof- is a user-written program from
http://www.ats.ucla.edu/stat/stata/ado/analysis/

The Statalist FAQ advises at
http://www.stata.com/support/faqs/res/statalist.html#stata

"Say what command(s) you are using. If they are not part of official
Stata, say where they come from: the STB/SJ, SSC, or other archives."

See -chitest- and -chitesti- from -tab_chi- (SSC) for alternatives.
The examples in the help files are pertinent.

Another alternative is to use Mata. Many chi-square problems reduce to
a few lines of Mata.
