Description:
Performs unconditional exact tests and power calculations for 2x2 contingency tables. For comparing two independent proportions, performs Barnard's test (1945) using the original CSM test (Barnard, 1947 ), using Fisher's p-value referred to as Boschloo's test (1970) , or using a Z-statistic (Suissa and Shuster, 1985, ). For comparing two binary proportions, performs unconditional exact test using McNemar's Z-statistic (Berger and Sidik, 2003, ), using McNemar's conditional p-value, using McNemar's Z-statistic with continuity correction, or using CSM test. Calculates confidence intervals for the difference in proportion. This package interacts with pre-computed data available through the ExactData R package, which is available in a 'drat' repository. Install the ExactData R package from GitHub at . The ExactData R package is approximately 85 MB.
