Ron�n, I've just examined the variables and all are numeric.

Dear All,
I get a "no observations" error message -r(2000)- when I execute a do
file,
and I'm having difficulty determining what's going wrong. According to the
error message, I "have requested some statistical calculation and there
are
no observations on which to perform it. Perhaps you specified if exp or in
range and inadvertently filtered all the data." I don't understand what is
meant by "filtered all the data". The line that generates the error
message
is:
regress lnW `varlist' if migst1==0
To check whether there are actually no observations, I gave the following
command (and had the shown output):
count if migst1==0 & !mi(`varlist')
2720
Is there a non-numeric variable in there perhaps?
