Performs unconditional exact tests and power calculations for 2x2 contingency tables. For comparing two independent proportions, performs Barnard's test (1945) <doi:10.1038/156177a0> using the original CSM test (Barnard, 1947 <doi:10.1093/biomet/34.12.123>), using Fisher's pvalue referred to as Boschloo's test (1970) <doi:10.1111/j.14679574.1970.tb00104.x>, or using a Zstatistic (Suissa and Shuster, 1985, <doi:10.2307/2981892>). For comparing two binary proportions, performs unconditional exact test using McNemar's Zstatistic (Berger and Sidik, 2003, <doi:10.1191/0962280203sm312ra>), using McNemar's Zstatistic with continuity correction, or using CSM test. Calculates confidence intervals for the difference in proportion. This package interacts with precomputed data available through the ExactData R package, which is available in a 'drat' repository.
