I am trying to create an esttab output similar to this:
Array


my code is as follows:
Code:
eststo kindergarten: reg test_score_k small_class_k reg_aide_k, r
eststo first: reg test_score_1 small_class_1 reg_aide_1, r
eststo second: reg test_score_2 small_class_2 reg_aide_2, r
eststo third: reg test_score_3 small_class_3 reg_aide_3, r

#delimit ;
esttab using table_11_1.rtf, title(STAR:Differences Estimates of Effect
on Standardized Test Scores of Class Size Treatment Group) mtitles("K" "1" "2" "3")
addnotes(Dependent variable is students combined math and reading of
the Standford AChievement Test) se(2) onecell equations(1);

How do I combine the regressors in the esttab table where there are only 2 regessors for all the regression outputs? The 2 regessors I want are small_class and reg_aide.
