Thank for this code, it is very comprehensive. However, when running this code, I get stuck at error at the line

 
 list _by1 _margin _se _ci_lb _ci_ub, noobs clean variable _by1 not found r(111);

How would I troubleshoot? I apologise for asking for such handholding, it's due to not recognising the methods you have suggested using.

The variable names must be different for you for some reason. Remove the variable list from the -list- command to see what they are (i.e., inspect the output from -list-), then modify the following code as needed.

 
 list, noobs clean

This is the output I get when using the data example I posted earlier in the thread:

 list , noobs clean

I am confused what each of the variables _by1 _marginn etc are supposed to be?
