```Richard and all,

Thanks for the feedback. My question is not so much, "How do I get Stata to
produce an e^b?" but more like "What formula does Stata use to produce the
e^b?" Here is the scenario that produced the question:

In checking the e^b with by hand calculations (FYI: my hand calculation are
based on a text book and while some e^bs were very close to being the same,
some were not), I found that the results were different when I calculated by
hand and with Stata. So the question is, what formula does Stata use?

Thanks :)
