RE: st: margins with post option

["Cohen, Elan" <cohened@upmc.edu>]

Thanks David & Richard.  -est store- & -est restore- worked.  Oddly, I had tried -est save- & -est use- earlier but was getting the following error when I tried to rerun -margins-: "e(sample) does not identify the estimation sample".

I was under the impression that store/restore worked the same as save/use with the only difference being whether the results were stored in memory or on disk.

Thanks again for your help,

- Elan
