- type: doi
  value: 10.32614/CRAN.package.ivcheck
abstract: Implements tests for the identifying assumptions of instrumental variable
  models, the local exclusion restriction and monotonicity conditions required for
  local average treatment effect identification. Covers Kitagawa (2015) <https://doi.org/10.3982/ECTA11974>,
  Mourifie and Wan (2017) <https://doi.org/10.1162/REST_a_00622>, and Frandsen, Lefgren,
  and Leslie (2023) <https://doi.org/10.1257/aer.20201860>. Includes a one-shot wrapper
  that runs all applicable tests on a fitted instrumental variable model. Dispatches
  on 'fixest' and 'ivreg' model objects.
