st: nlcom and delta method

Dear All,
I did a maximum likelihood, using delta method, to get the values.
So, for example, one result of my maximum likelihood using delta
method is this one:
. nlcom (a: 1/(1+exp(-[ar]_b[_cons])))
a: 1/(1+exp(-[ar]_b[_cons]))
------------------------------------------------------------------------------
| Coef. Std. Err. z P>|z| [95% Conf. Interval]
-------------+----------------------------------------------------------------
a | .3697282 .0196595 18.81 0.000 .3311963 .4082601
------------------------------------------------------------------------------
Now I wan to test a no linear combinations, using the coefficient of a
, however the usual command for the coefficient: _b[a] doesn't work.
What can I do in this case?
Thanks.
Best,
Bea
