There is an issue with the mean command in Stata 16, which does not exist in Stata 15.
Here is an example:
mean rel_percapgdp, over(war_year)
the variable war_year ranges from -20 to 20.
I get the following error message:
invalid over() option;
war_year: factor variables may not contain negative values
r(452);
The same command in Stata 15 provides valid results.
Any suggestions?
