Hi everyone,
I have panel data with a list of company ID's, years 2010-2020 and the industry that each country is in. When I do i.industry to attempt to include industry FE, all of the industries are omitted due to collinearity. Does anyone know why this would happen? My code is:
xtreg dv v1 v2 v3 v4 v5 i.year i.industry, fe
