I'd never heard of it before, but 
<http://en.wikipedia.org/wiki/Conway-Maxwell-Poisson_distribution> 
is informative.

Would a reference to Conway-Maxwell Poisson Regression help?  I'm not
sure what it is.  How does it differ from the usual Poisson Regression
Nick Cox
Official Stata [NB] can't do that, as consultation of the help and
manual entry for -glm- will show. 
-findit Conway-Maxwell- turns up nothing user-written. 
M. E.
I was wondering if anybody is aware whether Stata
has the capacity to estimate a Conway-Maxwell Poisson Regression within
its glm command?   If not, do you know of any updates or code to perform
this estimation in Stata?
