  value: 10.32614/CRAN.package.exact2x2
abstract: Calculates conditional exact tests (Fisher's exact test, Blaker's exact
  test, or exact McNemar's test) and unconditional exact tests (including score-based
  tests on differences in proportions, ratios of proportions, and odds ratios, and
  Boshcloo's test) with appropriate matching confidence intervals, and provides power
  and sample size calculations. Gives melded confidence intervals for the binomial
  case (Fay, et al, 2015, <DOI:10.1111/biom.12231>). Gives boundary-optimized rejection
  region test (Gabriel, et al, 2018, <DOI:10.1002/sim.7579>), an unconditional exact
  test for the situation where the controls are all expected to fail. Gives confidence
  intervals compatible with exact McNemar's or sign tests (Fay and Lumbard, 2021,
  <DOI:10.1002/sim.8829>). For review of these kinds of exact tests see Fay and Hunsberger
  (2021, <DOI:10.1214/21-SS131>).
