Hi all,

I have a cross-sectional dataset which contains info on 417 different funds. These funds belong to 50 fund management firms and belong to 33 different fund category. Each of the fund has a unique numeric fund size and also has a rating that falls between 1-5 (integer). I am trying to match each fund with a similar fund that belongs to a different management firm but has exact same category, exact same rating and similar size (the closest size would do the work). I tried psmatch2 but it can't do the work for matching within the same category. Any idea how I can achieve my goal most efficiently?

Thanks,
Vivian
