Either talk to the coeff as "_b" (-help _variables-) or define a -matrix-
and extract from it:
***********
sysuse auto, clear
reg price weight length rep78
di _b[weight]
mat A=e(b)
di A[1,1]
***********

Subject: st: Extracting specific elements from a matrix
Hi,
I need to extract the first element of a matrix of coefficients and store it
on a variable, and repeat the process i times. I can set up the for loop and
do the storing, but I don't know how to access element [i,j] of a matrix A.
In particular, my matrix is e(b), the vector of coefficients from a
regression with k explanatory variables. I tried -e(b)[1,1]- but that didn't
take me far.
Any help is appreciated.
Thanks,
DF Tilley
