Quasi Poisson regression analysis with spline terms

[Ishor]

I am trying to do Quasi Poisson regression analysis with spline terms for time series data ( predict excess mortality). Does anyone have macros or syntax. Thank you so much

Hello @Ishor ,

You need PROC COUNTREG from the SAS/ETS module.
ETS = Economic Time Series or Econometrics & Time Series

See here (and go to examples) :
SAS/ETS 15.2 User's Guide
The COUNTREG Procedure
https://go.documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/etsug/etsug_countreg_toc.htm

Look at COUNTREG and tell us if you need further assistance with the spline terms. You might need some pre-processing with another procedure for that (spline terms).

Good luck,
Koen
