Using GLIMMIX for APC analysis

[Jaiyong_Kim]

Hello.

I used GLIMMIX to do the age-period-cohort analysis.

CASE_NUM is number of cases.

LOGPOP is Log(Number of base population).

proc glimmix data=A ic=q;
class AGE(ref='50') PERIOD COHORT;
model CASE_NUM = AGE  /dist=poisson solution offset=LOGPOP;
random PERIOD COHORT /solution;
covtest glm/wald;
NLOPTIONS TECHNIQUE=NRRIDG;
; run;

My question is as follows.

1> Using GLIMMIX with random variables like this can avoid identification problems,

that is most big issues in APC analysis?

2> Can I find any examples using GLIMMIX for the APC analysis?

Regards..

Hi

I'm working on the same topic right now.

Were You able to find any useful examples of GLIMMIX for APC modeling?

Maybe anybody can point to the good ones, thank You in advance
