title: 'attrition: Addressing Nonignorable Attrition with Double Sampling and Bounds'
version: 1.0.0
doi: 10.32614/CRAN.package.attrition
abstract: Implements the double-sampling bounds estimator of Coppock, Gerber, Green,
  and Kern (2017) <https://doi.org/10.1017/pan.2016.6> for randomized experiments
  with nonignorable missing outcomes. Provides worst-case (Manski) bounds, double-sampling
  bounds with analytic variance and Imbens-Manski confidence intervals, Lee (2009)
  <https://doi.org/10.1111/j.1467-937X.2009.00536.x> trimming bounds with analytic
  and bootstrap standard errors, covariate adjustment via poststratification, and
  a sensitivity analysis for violations of the outcome stability assumption.
