pmamouris/ccoptimalmatch: Implementation of Case-Control Optimal Matching

An implementation of optimal case-control matching. It matches 1:n cases to controls in an efficient and computationally flexible way. It uses the idea of sub-sampling in the level of the case, by creating pseudo-observations of controls. The user can select between replacement and without replacement, the number of controls, and several covariates to match upon. See Mamouris (2021) <doi:10.1186/s12874-021-01256-3> for an overview.
