I was having the same issues as other users and getting the same error messages. Your instructions resolved these for me - thank you! I am now working on interpreting the results produced by STATA for example one however it is very unclear to me how results for class 1 through 5 (there are 2 matrix lists) resulted in the interpretations produced in the psu stata plugin handbook (https://methodology.psu.edu/downloads/lcastata). I need to understand this in order to understand how to then plug-in my own data and interpret the results. Your help is appreciated.
