How to use proc genmod to predict value in another dataset ?

[Dennis777]

Hi everyone, I am very new in sas and trying to predict value in SAS. I use a dataset from 2010-2019 as a baseline. I am wondering how I could predict the expect value in 2020.

here is my code below (use dataset from 2010-2019 to train):

Proc genmod data=all_data.data1;
class season ;
model death=season  old_a/ dist = poisson 
                      link = log
                      offset= ln
		      pscale
type1
type3;
ods output ParameterEstimates=PE;
run;

All I have is observe death. I want to obtain expect death in 2020.
