A program to compute the generalized Mantel-Haenszel chi-square for multiple 2 × J tables

Abstract

A FORTRAN program for computing the generalized Mantel-Haenszel χ²-test statistic for multiple 2 × J tables is presented. The output contains the additional information of expected cell values and the individual odds ratios for each stratum. For the case of 2 × 2 tables, an internal check of the expectation is made to assure that the asymptotic assumptions are met. Optionally, the Yate's correction for continuity can be employed for 2 × 2 tables. The program can handle frequency count data as found in contingency tables or fractional values as in life table procedures.
