EXACON: A Fortran 77 Program for the Exact Analysis of Single Cells in a Contingency Table

Abstract
A program named EXACON is presented which performs exact cellwise analyses of two-way contingency tables. EXACON is written in FORTRAN 77 and is interactive. One-tailed probabilities are computed for the observed frequency of each cell according to two different probability models, one being Fisher's exact test for a 2 x 2 table. Despite the fact that exact probabilities are computed, EXACON does not demand much computer time even for fairly large samples.
