As the author of -svrmodel-, I'd like to take a crack at this.

Could you have the folks at UCLA open a log file, -set trace on-, run the command, and then e-mail me (privately) the contents of the trace?

(It will be a super-long output file, but that's OK).

I am analyzing data from the California Health Interview Survey, but am not
allowed to have the real data.
I send my programs to the Data Programmers at UCLA and they run them for me.


Every time they run the following SVR regression on black men, I get back a
conformability (r503) error:

xi: svrmodel activity  i.age i.nativity intEnglish i.neweduc married
employed density stability ses4 immigrant if male=1&race==3

Because I do not have access to the data, what should I do? How can I figure
out where I have missing values and where the problem lies? I can send the
programmers at UCLA any commands or programs, but am not sure what to do.
This does not occur in the dummy data set I have, so I can't really explore
the problem using the fake data.

I only get it on this regression for black men and no other one......other
regressions with black men and different outcomes work fine.

Thanks,
