Just look at the instructions that you have given to Stata: You want the
-rownames- to be equal to your "varlist" -local- so that is what you get.
Stata repeats the second entry in the -local- as often as it needs to to
fill the matrix rows. Your problem might be easily solved via -statsby-, by
the way...

Subject: st: matrix out
Hello, I'm trying to obtain a matrix using the following code:
*********************************************
local varlist "strokeriskNULL strokeriskP55"
matrix out = J(20,3,-99)
matrix colnames out = risk sex age
matrix rownames out = `varlist'
local irow = 0
foreach var in `varlist' {
foreach i in 2 3 4 5 6 {
foreach s in 0 1 {
local ++irow
qui mim, storebv: svy: regress `var' if sex==`s' & ageg==`i'
matrix A=e(b)
matrix out[`irow',1]=A[1,1]
matrix out[`irow',2]=`s'
matrix out[`irow',3]=`i'
}
}
}
matrix list out
*******************
I expect to get ten lines starting with "strokeriskNULL" and ten starting
with "strokeriskP55". However I get only the first line starting with
"strokeriskNULL" and the remaining 19 starting with "strokeriskP55".
Could anybody point me to what's wrong with these instructions?
Very thankful,
Mauricio Herrera.
