extract coef,se,t,pv from stata reg

Maarten Buis’s method to extract estimate from stata reg

——-begin correct code —
sysuse auto, clear
reg price mpg rep78 headroom trunk weight
matrix a = vecdiag(e(V))
matrix b = (e(b)\a)’
svmat b
rename b1 beta
gen se = sqrt(b2)
gen t = beta/se
gen p = 2*ttail(63,abs(t))
——— end correct code—–
