Hi everyone,

I am trying to run some old code (version 14.2) using a new Stata version (15.1) on a different computer. My issue is that when I run a regression analysis using the automatic dummy variable option (e.g., i.var) for some reason the regression output includes the reference category (albeit not always as you might notice with i.sex). Please see the image for an example (not the full analysis, but demonstrates the issue). I have not changed the code at all (nor the data) since the last time I ran the code using the old Stata version.

Any insights on how to solve this problem?

Thank you!
