tightenBlock

Tightens an observational block design into a smaller design with either smaller or fewer blocks while controlling for covariates. The method uses fine balance, optimal subset matching (Rosenbaum, 2012 doi:10.1198/jcgs.2011.09219) and two-criteria matching (Zhang et al 2023 doi:10.1080/01621459.2021.1981337). The main function is tighten(). The suggested 'rrelaxiv' package for solving minimum cost flow problems: (i) derives from Bertsekas and Tseng (1988) doi:10.1007/BF02288322, (ii) is not available on CRAN due to its academic license, (iii) may be downloaded from GitHub at https://github.com/josherrickson/rrelaxiv/, (iv) is not essential to use the package.
