I am trying to test equality across quantiles after using the qregpd command in stata (quantile regression for panel data with fixed effects). My problem is that i am unable to run the command for multiple quantiles at once, so i am not able to run the code "test [q25]var=[q50]var=[q75]var" after running the regression like I would be if I used a qreg or sqreg command. I have to run 3 individual regressions for each quantile im looking at (25,50,75). My question is how can I test across quantiles when they are reported individually in tables? Thank You in advance for your help!
