Paolo is using an older version of -genhw- which failed when any of the
allele frequencies were equal to zero. Verify this by typing:
. which genhw
c:\ado\stbplus\g\genhw.ado
*! version 7.0.0 10dec2002
Paolo can install the newest version which is available on my website
www.biostat-resources.com/stata/index.htm or simply type -findit genhw-
within Stata, and follow the links for "genhw from
http://biostat-resources.com/stata";.
If Paolo's polymorphisms are all SNPs then he may also want to download
and install -hwqtl- which is use to perform Hardy-Weinberg equilibrium
tests for multiple SNPs, which is what I think Paolo is trying to
program.
Regards,
Mario.
