Good question. I started with . set trace on . set traced 1 and ran your example. I think I had to bump up to -set traced 2-. This way I found that -_pepred- was complaining and checked that the problem lay in your call being rejected by its -syntax- statement. This looked like a helper program but a check showed that it has its own help file. So it's easy!

The restriction is documented, but you need to look at the specific help file. I don't know of any arguments for this except convention, but you need to ask the authors. > > Nick > > On Thu, Sep 1, 2011 at 3:22 PM, MacLennan, Graeme <g.maclennan@abdn.ac.uk> wrote: >> I am using -prvalue- from -spost- version 9 from http://www.indiana.edu/~jslsoc/stata (-findit spost-) to get predicted probabilities and differences after using -ologit-. The command -prvalue- has a -level(#)- option to specify the width of confidence intervals. I wanted to use 97.5% Cis but it would appear that only integer values are accepted? The following syntax tells me that "option level() incorrectly specified" and "invalid syntax" repectively. If this can be reproduced, I will send off an email to the address in the help file.
