Thanks to Kit Baum, two packages have been updated
on SSC. 


This is a bundle of tabulation and chi-square programs. 

-chitest- and -chitesti- are for univariate chi-square 
tests, as when you want to compare digit frequencies 
with a uniform distribution, or genetic frequencies 
with Mendelian predictions, etc. They have been 
updated to Stata 8, and the results are now presented 
making good use of the new -list- features. The help files 
have also been improved, with better examples and documentation
of pertinent tricks. 

At the same time, the previous versions, written for 
Stata 6, remain on SSC for the convenience of any interested 
users of Stata 7 or Stata 6. (If any such installed -chitest- 
and -chitesti- after July 2000, they are missing nothing they 
can make use of by not installing now.)  

. ssc desc tab_chi 

describes what is the package, including other programs. 
(Additions to -tabulate- in Stata 8 do not, by the way, 
make -tabchi- or -tabchii- obsolete, as they continue 
to offer features not supported by -tabulate-.) 


This graphics program, for Stata 8, posted recently 
has been revised and improved. In particular, 
if you installed -onewayplot- on its first posting, 
please upgrade. (The first version contained a bug 
identified by Phil Ender.) In any case, 

. ssc desc onewayplot 

and (longer) 

. ssc type onewayplot.hlp 

give a fuller explanation.
