Hello Steve, I have used countreg statement for my negbin random and fixed effect modeling. I had some error and warning saying "Warning: Optimization cannot improve the function value". Can I use hpcountreg, would that help to find an output without error? My hpcountreg coding is not running. I have used proc hpcountreg data=Panel groupid=id; performance nthreads=2 nodes=1 details; model PDO = ADT_Maj ADT_Min L_Maj L_Min LL_Maj LL_Min RL_Maj RL_Min Med_Maj Med_Min park skew Rain Snow ydr dui/dist=negbin errorcomp=fixed; run; Would you please check, what is wrong with my coding?
