Dear all
I would like to use poisson regression to calculate PR (prevalence ratio). The command I used was poisson y x1 i.x2,irr. However, some article recommended that to calculate PR with poisson regression, we should use robust. However, in some cases, regression with robust gives the results significantly otherwise not. Can you recommend me which one I should use.
Thanks so much
