%description
Natural strata can be used in observational studies to balance the
distributions of many covariates across any number of treatment groups and
any number of comparisons. These strata have proportional amounts of units
within each stratum across the treatments, allowing for simple
interpretation and aggregation across strata. Within each stratum, the
units are chosen using randomized rounding of a linear program that
balances many covariates. 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>.
