I am basically using 2 different implementations of PSM (one in the CEM package, and the other is in the MatchIt package). I realized that there are many parameters for PSM that can be turned on and off. To be more concrete below is a short list of parameters and I have some preliminary results indicating that these parameters change the performance of the PSM matching (i.e., the L1 imbalance value): --match with/without replacement --breaking ties when the distance is same for multiple control instances --matching ordering My question is that, given there are many knobs especially for PSM, what are the right settings for these parameters to fairly compare the performance against the performance of CEM? Thanks.
