  "Description": "Performs multilevel matches for data with cluster- level\ntreatments and individual-level outcomes using a network\noptimization algorithm.  Functions for checking balance at the\ncluster and individual levels are also provided, as are methods\nfor permutation-inference-based outcome analysis.  Details in\nPimentel et al. (2018) <doi:10.1214/17-AOAS1118>.  The optmatch\npackage, which is useful for running many of the provided\nfunctions, may be downloaded from Github at\n<https://github.com/markmfredrickson/optmatch> if not available\non CRAN.",
