Description
Optimally Refine Strata.
Description
Splits initial strata into refined strata that optimize covariate balance. For more information, please email the author for a copy of the accompanying manuscript. To solve the linear program, the 'Gurobi' commercial optimization software is recommended, but not required. The 'gurobi' R package can be installed following the instructions at <https://www.gurobi.com/documentation/9.1/refman/ins_the_r_package.html>.

optrefine
The goal of optrefine is to split existing strata (or none) into more refined strata that optimize covariate balance. Most often, propensity score strata are each split into two in order to achieve better covariate balance.
