When you say a cross-country analysis, do you mean that each country is a 
unit of analysis? If so, then the number is a bit small for the robust 
option. (For alternatives, you might like to investigate the use of 
quantile regression (qreg, sqreg)). If there are many units within a 
country, then you might want to consider some kind of multi-level 
analysis, eg xtpoisson.

st: RE: Appropriate number of samples for POISSON regression with ROBUST 
option






Hello,

I’m trying to conduct a cross-country analysis using POISSON with ROBUST
option. The results of the regression are consistent with my expectation. 
 

However, the number of samples used in the analysis is only 45 countries.
I’m wondering whether the number is appropriate to conduct the poisson
analysis.

Thanks

Jun
