is the total number of attributes where A has value 0 and B has value 1, and M 10 {\displaystyle M_{10}} is the total number of attributes where A has value 1 and B has value 0. The simple matching distance (SMD) , which measures dissimilarity between sample sets, is given by 1 − SMC {\displaystyle 1-{\text{SMC}}} .
Choose appropriate confounders (variables hypothesized to be associated with both treatment and outcome) Obtain an estimation for the propensity score: predicted probability p or the log odds, log[p/(1 − p)]. 2. Match each participant to one or more nonparticipants on propensity score, using one of these methods: Nearest neighbor matching

That is, where the i th nearest neighbour is assigned a weight , with = =. An analogous result on the strong consistency of weighted nearest neighbour ...
