How to fix ERROR: Error in estimation routine on SAS Studio OnDemand for Academics

Joa14 — Fri, 02 Aug 2024 02:41:02 GMT

I am using the Tasks Option on SAS Studio On Demand and choosing Linear Models → Generalized Linear Models and running the model with Distribution: Zero Inflated Negative Binomial. The problem is that the Wald Chi-Square and the Pr > ChiSq results are blank. I expect these rows to have values. Some variables ran successfully on their own but fail when combined with others. Additionally, models that previously ran without issues are now failing generating the same error. The error message is: ERROR: Error in estimation routine (See the Log and Screenshot of results attached). All help would be greatly appreciated. Thanks!

The Log is:

		resraw(index) );
	model BPSdCnt=EricShrRA CO / dist=zinb;
	zeromodel EricShrRA CO;
run;

Please do not double-post.

Have you checked this:

WARNING: The specified model did not converge.

This may cause such procedures to run into infinite loops.

I have not. I have seen another warning when running the models: WARNING: Negative of Hessian not positive definite.

There are too many reason to produce this NOTE.
Check this paper at page 10.
NOTE: Convergence criteria met but final hessian is not positive definite.
