  "Description": "Implements popular methods for matching in time-varying\nobservational studies. Matching is difficult in this scenario\nbecause participants can be treated at different times which\nmay have an influence on the outcomes. The core methods\ninclude: \"Balanced Risk Set Matching\" from Li, Propert, and\nRosenbaum (2011) <doi:10.1198/016214501753208573> and\n\"Propensity Score Matching with Time-Dependent Covariates\" from\nLu (2005) <doi:10.1111/j.1541-0420.2005.00356.x>. Some\nfunctions use the 'Gurobi' optimization back-end to improve the\noptimization problem speed; the 'gurobi' R package and\nassociated software can be downloaded from\n<https://www.gurobi.com> after obtaining a license.",
