  "Description": "Provides functions to perform matching algorithms for\ncausal inference with clustered data, as described in B. Arpino\nand M. Cannas (2016) <doi:10.1002/sim.6880>. Pure\nwithin-cluster and preferential within-cluster matching are\nimplemented. Both algorithms provide causal estimates with\ncluster-adjusted estimates of standard errors.",
