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.

Thank you so much, Ksharp. I stopped using the software for several hours, and then when I tried again, it worked without putting your suggestion. However, now I get a warning that does not allow p-value and St Err to show in the summary box. As you can see in my previous graph, it worked (at least I could see the values), but now it does not. I wonder if it is a software issue. See the warning below. Any suggestion would be appreciated.   WARNING: Apparent symbolic reference PROBT not resolved. 229 "St Error"="&StdErr" WARNING: Apparent symbolic reference STDERR not resolved. ... View more

Thank you so much, Ksharp.   I did try your code but it did not generate what I wanted. I found another one in this link https://support.sas.com/kb/65/202.html but the box with the summary is not shown correctly (as shown in the image). Any suggestions?   ... View more
