Thanks to both Red Owl and Joseph Coveney for the response!

That error message is easy to misunderstand. I assumed (wrongly) that the
error was referencing the binary variable used in by(), not in missing
levels of the strata...

Joseph, FYI, I emailed you at [email protected] on 12/29/13 and then
again at [email protected] on 1/1/14. I did not receive a notification of a
bounce either time...

Sorry about the misunderstood error message.  I suppose that it's like the 
"no observations" error message that you can get from some official Stata 
commands that seems curious at first.  

Regardless, I recommend using the -emh- command in lieu of -vanelteren- for 
performing van Elteren's test.  I've posted at least a couple of times on
this
list how to do it, but if you need a handy permanent reference as to how,
you 
can take a look at the FAQ on the same topic by SAS for its PROC FREQ at 
http://support.sas.com/kb/25/022.html .  You'd use the analogous options
with
- -emh-, that is,

    PROC FREQ; 
      TABLES STRATA * TREATMENT * RESPONSE / CMH2 SCORES=MODRIDIT NOPRINT; 
    RUN;

becomes

    emh response treatment, strata(strata) anova transformation(modridit)

You can download and install -emh- from the same source as you got
-vanelteren-.
- -emh- can do everything that the older -vanelteren- can, and much more
besides.

Checked again, and no hits.  I can see how the bigplanet account might not
have
had anything--it has a "Postini" spam filter on the mail server that can get

pretty aggressive.  But I can't explain why the gmail account doesn't have
anything from you on the fourteenth except your Statalist post on
subscripting.
