title: 'tightenBlock: Tightens an Observational Block Design by Balanced Subset Matching'
version: 0.1.7
doi: 10.32614/CRAN.package.tightenBlock
abstract: '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 <https://doi.org/10.1198/jcgs.2011.09219>)
  and two-criteria matching (Zhang et al 2023 <https://doi.org/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) <https://doi.org/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.'
