I have an old Mx question that I was hoping to get help with. I was able to get an ordinal univariate model to run, but am now having a difficult time getting the confidence intervals to work. The error statement I am receiving is:
Hmmmm. The lower bound for this integral is greater than or equal to the upper bound.
This will cause problems with the likelihood function.
Please check your thresholds are bounded appropriately
I've tried changing the boundary estimates as well as the thresholds and nothing seems to work. Any advice would be greatly appreciated. I attached the script and dat file. Thanks!
