Exact Tests and Confidence Intervals for 2x2 Tables

Description

There are 8 main functions in the package. The exact2x2 function calculates the exact conditional tests with matching confidence intervals as detailed in Fay (2010a <DOI:10.1093/biostatistics/kxp050>,2010b). The functions ss2x2 and power2x2 calculate the sample size and power related to the tests of exact2x2. The uncondExact2x2 and boschloo functions calculate unconditional exact tests (see Fay and Hunsberger, 2021, <DOI:10.1214/21-SS131>). The binomMeld.test function calculates melded confidence intervals for two sample binomial inferences (see Fay, Proschan, and Brittain, 2015 <DOI:10.1111/biom.12231>). Finally, the borrTest function calculates the boundary optimized rejection region test that creates unconditional exact tests that have power optimized when group 1 is expected to have 100 percent failure. For example, in vaccine challenge studies where the control group are all expected to get infected (see Gabriel, et al, 2018 <DOI:10.1002/sim.7579>, the letter about that paper by Martin Andres <DOI:10.1002/sim.7630>, and the response <DOI:10.1002/sim.7684>). The mcnemarExactDP function give p-values and confidence intervals compatible with exact McNemar's or sign tests (Fay and Lumbard, 2021, <DOI:10.1002/sim.8829>).
