Performs multilevel matches for data with cluster- level treatments and individual-level outcomes using a network optimization algorithm. Functions for checking balance at the cluster and individual levels are also provided, as are methods for permutation-inference-based outcome analysis. Details in Pimentel et al. (2018) doi:10.1214/17-AOAS1118. The optmatch package, which is useful for running many of the provided functions, may be downloaded from Github at if not available on CRAN.
