I have very large dataset with over 6M records. I didn't get the error message when I run the code with the full dataset, but it took too long to run.

I appreciated for any suggestion or advice.    proc genmod data = mydata; class recruited_18(param=ref ref='0') dual_18(param=ref ref='1'); model adm_18 =recruited_18 dual_18 /dist=zinb type3 offset=ldays; zeromodel ldays/link=logit; run; ERROR: Floating Point Overflow. ERROR: Termination due to Floating Point Exception NOTE: The SAS System stopped processing this step because of errors. ... View more
