  "Description": "Implements the Stable Balancing Weights by Zubizarreta\n(2015) <DOI:10.1080/01621459.2015.1023805>. These are the\nweights of minimum variance that approximately balance the\nempirical distribution of the observed covariates. For an\noverview, see Chattopadhyay, Hase and Zubizarreta (2020)\n<DOI:10.1002/sim.8659>. To solve the optimization problem in\n'sbw', the default solver is 'quadprog', which is readily\navailable through CRAN. The solver 'osqp' is also posted on\nCRAN. To enhance the performance of 'sbw', users are encouraged\nto install other solvers such as 'gurobi' and 'Rmosek', which\nrequire special installation. For the installation of gurobi\nand pogs, please follow the instructions at\n<https://docs.gurobi.com/projects/optimizer/en/current/reference/r.html>\nand <http://foges.github.io/pogs/stp/r>.",
