Hi,

I'm looking to get some assistance understanding the output of a postestimation command, estat vce, corr when applied following a negative binomial model that includes random slope and intercept. Specifically, I am looking for the covariance between the random intercept and the random slope - expressed as a correlation coefficient. However, I am currently not able to understand the output and am unclear on which number is the coefficient for the covariance between the random slope and random intercept. I cannot find any annotated output for the estat vce command for a model that includes random slopes and intercepts. Any help would be very appreciated!

Code:
menbreg DrugNumber admdis || mrn: admdis, vce(robust) irr covariance(unstructured)
estat vce, corr
Here are mock-ups of what the results look like, if that is helpful.
Output from the menbreg command:
Array

And the output from the estat vce, corr command looks like:
Array
Thanks so much!
