In order to answer that question we need to know what you did, which
is probably described in that working paper, but given that reference
it is impossible for us to find it, and thus it becomes very hard to
answer your question. Please see the Statalist FAQ (a link to it is at
the bottom of every post on Statalist) and comments from Cox (2011)
and Buis (2011)(*).

A general comment that may help is to do the computation using
-nlcom-, see -help nlcom-, as that will use the delta method for you.
