st: Grouped Logit question

[Fredrik Wallenberg <fredrik@sims.berkeley.edu>]

Revealing my ignorance of the mathematical proofs, I'm struggling to 
get a grip on exactly what the Grouped Logit function does and how it 
should be used appropriately. Specifically I wonder about the use of 
count vs. proportion variables on both the left and right hand side.

the command is (of course)

glogit depvar denominator list_of_covariates

Also, I assume that what this does (in layman terms) is essentially 
weight each row by the relative size of that observation compared to 
the size of the other observations. In my case I have observations by 
county and running the regression for the full US... i.e. I have some 
3200 observations representing all use households.

Thanks in advance,

Fredrik
