st: Question on -Areg- command

[lena Lindahl <lena.Lindahl@sofi.su.se>]

Hi!
I have a question on the -Areg- command.
In the STATA manual it is used in the following example:

areg mpg gratio, absorb(rep78).

I would like to run a regression with a very large amount of dummy 
variables.
Using the example, I would like to run the regression without the right 
hand side variable, gratio, and so only estimate the effect of the 
absorbed dummy variables represented by rep78. (I am only interested in 
the adj R2 value.) But it is not possible to leave out variable gratio, 
the error message states  "varlist required".

Anyone who has an idea?

All the best/
Lena
