I am trying to obtain the marginal effect after using gllamm.

I have looked at prior posts which explain that one cannot use the command mfx

and one should instead use the command gllapred.

However, I don't quite see how it is equivalent.

I am putting an example next that I ran with STATA 10.

use

http://www.ats.ucla.edu/stat/paperexamples/singer/hsb12.dtagen gm = (matach > 10)

logit gm minority female

mfx

gives me

variable | dy/dx Std. Err. z P>|z| [ 95% C.I. ] X

---------+--------------------------------------------------------------------

minority*| -.2380667 .01292 -18.43 0.000 -.26339 -.212743 .274739

female*| -.0772496 .01146 -6.74 0.000 -.099714 -.054785 .528184

------------------------------------------------------------------------------

I would like to be able to replicate this with gllamm, just to make

sure that I understand

what I am doing.

gllamm gm minority female , i(one) link(logit)

gllapred pred, mu marg

Now my question is how do I go from here to obtaining the coefficient

for dy/dx and Std.Err.

that I obtained with mfx?
