Hi all.  With thanks as usual to Kit Baum, an update to -ranktest- is
available.

The update (ver. 1.2.05) fixes a nasty bug introduced in last month's
update (ver. 1.2.04) that messed up results when using weights of all
sorts.

-ranktest- is used by -ivreg2- and -xtivreg2- to generate under- and
weak-identification statistics, so if you are users of these programs,
you should definitely update in the usual way (net install
ranktest.pkg).

Apologies for the bug.  I've added weight tests to the cert script, so
this particular problem shouldn't happen again.
