EXTSIG

Exact P-Values for 2 X 2 Tables

Description

EXTSIG provides exact p-values for a test of a difference between two binomial proportions as well as the usual chi-square value and Fisher's p-value. The exact test uses a sorted outcome space. Exact tests have the advantage that (1) significance levels are as stated, and (2) power tends to be greater than with the chi-square or Fisher's test.
