Hi,

I ran the code for a Friedman's test comparing multiple variables: https://www.stata.com/statalist/arch.../msg00691.html

However I cannot get it to work (while I did save my file before running the code). How can I get this code to work?I have a panel data set and I want to compare 11 interaction variables that I have (dummy x independent variable). Or if this is not possible, I would like to use the group variable which is used for creating the 11 dummies and then check differences between these groups. When I try to run the code on the interaction variables, it says: / invalid name.

How could I get this code to work? It seems to be exactly what I want, as I want to compare all groups individually (group 1 with group 2, group 1 with 3 etc.) but I cannot get it to work.

Thanks in advance.
