Hi,

I'm modeling costs using -glm- in STATA.  This is how my syntax looks:

glm cost var1 var2 var3, family(gamma) link(log)

My primary interest variable is var1 which is a 0/1 dummy variable.  My
understanding is that the coefficients on the right hand side variables will
be in logs.  Now, how do I convert these coefficients into actual dollars?
Meaning, how can I say that var1=1 is so much more (less) in dollars
compared to var1=0.  Can I also get 95% CI around the mean dollar estimate
for va1?  I do not use STATA very often so providing actual syntax will be
of much help.
 
Thanks.

Puneet
