Bob,

Was their model also a count model or did they transform to meet the
normality assumption of OLS?

Dear All,

I'm about to embark on an  analysis using count models to replicate a
study 
in which the authors log  transformed or used some other transformation
on 
their regressors prior to  estimating their models. I was under the
impression 
that typically one begins  with untransformed variables in count models,
assess 
the fit, and then -- if  necessary -- transforms regressors. 

Any thoughts on these  approaches?

Thanks in advance.
