Greetings,

I am modeling healthcare costs using a glm with gamma
distribution and the log link:

glm y x1 x2 x3, fam(gamma) link(log)

The coefficients are displayed in log terms. When I
predict the mean costs for the sample {mu as the
default; y_hat = g_inverse(xb)}, the means are
displayed in monetary terms as desired.

How can I obtain the 95% confidence intervals for the
predicted means?  I've tried the command:

predict se_mean, stdp

but this does not give me the SE's around the
predicted means.

Thanks in advance for help.

Mike
