I've tried to repeat the following process:
forvalues i=1990(1)2013 {
reg a b c if year==`i',r
est sto G`i'
}
However, Stata regress and doesn't store the coefficients of each regression. Probably, forvalues
isn't the best command to do that, but I don't know which coding is better.
esttab
in your question. Note thatest sto
andeststo
are different commands. – Nick Cox
