Abstract: matchit is a tool to join observations from two datasets based on string variables which do not necessarily need to be exactly the same. MatchIt implements the suggestions of Ho, Imai, King, and Stuart (2007) for improving parametric statistical models by preprocessing data with nonparametric matching methods. MatchIt implements a wide range of sophisticated matching methods, making it possible to greatly reduce the dependence of causal inferences on hard-to-justify, but Hi Statalisters, I try to use fuzzy match commands matchit and reclink to merge two datasets. Here is an example of master file.

Approximate matches I am running a matching procedure in R, using the MatchIt package. I use propensity score match, that is: estimate treatment selection by logit, and pick the nearest match.
