摘要：
For cases in which a parameter may be estimated from several independent data sets, Mather (1935) proposed a heterogeneity test based on the efficient scores for the individual data sets evaluated at the overall maximum liklihood estimator. Following Fisher (1946), a modification of the heterogeneity score test is presented wherein a consistent but inefficient estimator of the parameter of interest is substituted for the overall maximum likelihood estimator. The modified test is derived using the C(.alpha.) theory of Neyman (1959). Using the modified procedure, a test is derived for a common odds ratio in several 2 x 2 tables based on the Mantel-Haenszel estimator.
