Dear Statalists,

I’d appreciate your thoughts & help to overcome a roadblock: I have count data for rare events over 4 complete years and I’d like to prove that what happened during 2 months of current year (data up to date) is statistically different. How would you approach this question?

I thought of a Panel Poisson regression / probability estimate (ID: year, time: month), month as FE. From there on I cannot see the way to answer my question...

thank you for your time and help in advance.

Stefanos
