Mantel-Haenszel-type tests for testing equivalence or more than equivalence in comparative clinical trials
T Yanagawa, T Tango, Y Hiejima - Biometrics, 1994 - JSTOR
This paper proposes Mantel-Haenszel-type statistics for testing whether a new treatment is
at least as effective as the standard treatment in comparative binomial trials. The null …

Sample size requirements for stratified prospective studies with null hypothesis of non‐unity relative risk using the score test
JM Nam - Statistics in medicine, 1994 - Wiley Online Library
The standard test of the null hypothesis of unity of the relative risk seeks to determine if two
treatments differ. It does not apply when the requirement is either to establish the …

On approximate and exact sample sizes of equivalence tests for binomial proportions
H Frick - Biometrical journal, 1994 - Wiley Online Library
There exist several formulae for sample sizes for testing the equivalence of binomial
proportions which are based on approximations by the normal distribution. Quite often these …
