title: 'hbal: Hierarchically Regularized Entropy Balancing'
version: 1.2.15
doi: 10.32614/CRAN.package.hbal
abstract: Implements hierarchically regularized entropy balancing proposed by Xu and
  Yang (2022) <https://doi.org/10.1017/pan.2022.12>. The method adjusts the covariate
  distributions of the control group to match those of the treatment group. 'hbal'
  automatically expands the covariate space to include higher order terms and uses
  cross-validation to select variable penalties for the balancing conditions.
