My question is a two parter
-I am attempting the below regression using twelve controls. Is it possible to represent these twelve variables into a vector, let's say "X". I tried to generate a new variable using these and it did not work.

-For my second part. When using estout, is it possible to control what variables go into the table? For instance if I did the entire above regression and only wanted two variables reported.
