Many thanks

Others have made useful comments on this issue, but I would point out that the best way of generating a numlist (without so much typing) would be something like

webuse auto,clear
local list
forv i=1/5 {
summ price if rep78==`i',meanonly
local mu = int(r(mean))
local list "`list' `mu'"
di "`list'"

In re ipshin (as a coauthor of that routine) if you run the first example in the help file and then do:

. return list

r(pval) = .9999988489391395
r(psi) = 4.724914519654275
r(cv1) = -2.18
r(cv5) = -1.99
r(cv10) = -1.88
r(tbar) = -.0703609499728209
r(T) = 26
r(N) = 10
r(nobs) = 23

r(determ) : "constant"
r(lags) : "2"
r(depvar) : "rgdppc"

You will see what is being returned by the routine.
