If those output fuzzy sets are different, the aggregation can be done simply by placing all the truncated functions together to form the final fuzzy. One important detail that may not be clear from the answer above is that the default form of matching in the matchit package (and in much of the scholarly literature in any field) is to use a propensity score that estimates, for each observation, the probability of assignment to treatment given some set of pre-treatment covariates using logistic regression. In fact, there are many kinds of fuzzy-merges. Fuzzy thresholding aims at defining membership functions for regions, based on a set of thresholds [39][14].
