But I think they are only for two groups

Re: Matching/propensity scores for 3 groups
Hi Dale,
Yes, stata does have a routine. I don't recall it's name but maybe check
the stata website. I don't use stata but somebody whose work i was
reviewing did use it. The project had two groups so i don't know whether
the stata routine can accomodate three groups.

Subject: Matching/propensity scores for 3 groups
Greetings.......I have used the SPSS macro (that I believe is discussed in
an article in Behavior Research and Methods) that uses propensity scores
(via binary logisitic regression) for matching two groups; however, I am
currently on a study that necessitates matching on three groups. So I was
curious what any of you have done for matching three groups using SPSS (I
will be matching on sex, Length of stay, and # of comorbidities)? Do you
think it would be problematic to use propensity scores from a multinomial
logistic regression (and insert such in the macro?). Or will that just
give me two sets of propensity scores (e.g., grp 1 vs grp 2; grp 1 vs grp
3, etc.)?
Otherwise, I do have Stata but have not used it for matching
purposes.......if SPSS is not equipped for 3 group matching, do you know
if Stata has a package that does such?
thank you very much in advance for any suggestions.....dale
