st: standard error of prediction (with weights)

["Hans Olav Melberg" <hans.melberg@gmail.com>]

When using the following:

logit c6 $x6 [pweight=w2all], or
mfx compute, at(gateway=0)

I get:
Marginal effects after logit
      y  = Pr(c6) (predict)
         =  .00067379
etc

How do I find standard error of the predicted value?

The predicted value (y = 0.00067) is calculated using weights as well
as at the mean of the variables, except for one variable which is 0.
I found some commands that might be useful, but they did not accept weights.
