Hi, I have a panel dataset of with a variable country, year, university, sat score. (Similar variables)
I want to do TWO individual
reg3 (fees applicationratio_df sat) ( applicationratio fees_df sat)
for two time periods each (i.e 2000-2010 and 2011-2020) to compare their coefficients and p-values.
I also want to see the difference in full reg3 regression for country sets i.e (US, Rest of world without US)
