Dear Nick:
Sorry to bother you. I tried without the spaces and I get the same error message.
Anyway, I perfectly understand your message. The program you designed works perfectly and solved the problem.
(One more word on -makematrix-. Again, I understand what you say. Please, don't be at a loss because of me. I simply liked -makematrix- because I feel more independent - including from statalisters - with this command and I can adapt it to many descriptive statistics and univariate tests, which are very important in my field, financial accounting. With the solution of already designed commands, I don't have the same freedom, because I don't know how to program and modify them, if would like to. That's all).
Thanks again for your time.
Best regards
Herv�

Your answer strengthens my previous argument.
-makematrix- just cannot fulfil all the expectations
you have of it. If you omit the spaces in
max(chiprob(r(df), r(chi2_adj) + 1e-20),.0001)
to
max(chiprob(r(df),r(chi2_adj)+1e-20),.0001)
you might get -makematrix- to behave the way you want,
as the argument of -from()- is parsed on spaces,
but you are still ignoring my strong advice not to do it
this way.
I am at a loss to see why you prefer this route to
that of a program designed to tackle your problem
directly. No programming on your part is required.
