Dear Statalisters,
i want to create a control group for an Treatment group.
this Syntax make nearly what i want. But is it possible to match 2
Neighbours to each person from the treatment group (1:2)?
************
pscore treatment x1 x2, pscore(p) blockid(blockf1) comsup level(0.001)
set seed 1000
gen x = uniform()
sort x
psmatch2 treatment, pscore(p) neighbor(1) ate noreplace caliper (.01)
sort _id
gen match = id[_n1]
gen treat = id if _nn == 1
drop if treat == .
tab treatment
**************
Thanks, Jörg
