Hi Maarten, thanks for the clarification.  Looks like it worked but need to
look more closely.  I'll let you know if any doubts.  Thanks. Puneet

Puneet:
You stated that: "My understanding is that the coefficients on the right
hand 
side variables will be in logs." -glm- will model the log of costs as a
linear 
function of var1, var2, and var3. All this is done by -glm-, you don't need
to 
do anything. -mfx- will automatically show the effect of the explanatory 
variables on costs in dollars, and it will automatically detect dummy
variables 
and show the discrete change. So literally all you need to do is issue your 
-glm- command on the untransformed cost variable and than type -mfx-. You
can 
copy the example code I sent in my previous post in do file editor and run
it 
to see what it does. 

HTH,
Maarten
