I never even try to guess the names, but just -matrix list e(b)- to
see what they are. And then you can incorporate them into the syntax
of -test- as Michael explained.
. qui sureg (price length weight) (mpg length weight)
. mat li e(b)
e(b)[1,6]
price: price: price: mpg: mpg: mpg:
length weight _cons length weight _cons
y1 -97.960312 4.6990649 10386.541 -.07959347 -.00385148 47.884873
