Mark answered:
You need to do it in several steps, e.g.,
mat m=e(first)
scalar shea=m[1,1] /* or whatever is the correct column */
eret2 scalar partr2=shea
In fact, this can be done in one step using Stata's el() matrix
function (see -help matrix functions-). Type
. estadd scalar partr2 = el(e(first), 1, 1)
ben
[-eret2 scalar partr2 = el(e(first), 1, 1)- would also do]
