Best answer

It is a special case of matching: the distance metric is the (estimated) propensity score

1-to-n nearest neighbor matching is common when the control group is large compared to treatment group


intuitive, robust, matched pairs, balance distributions in directions uncorrelated to estimated PS


  • much tuning: with or without replacement, 1-to-1 or 1-to-n, caliper, ties
  • programming is hard
  • difficult to extend to complex situations: sequential treatments, multi-valued treatments
