Testing Simultaneous Marginal Homogeneity in Clustered Matched-Pair Multinomial Data

For matched-pair data with a multinomial reponse, the Stuart-Maxwell
test (1955, 1970) and the Bhapkar test (1966) are commonly used to test the
marginal homogeneity. However, in medical research, many studies for assess-
ing safety consider multiple multinomial endpoints to detect the treatment ef-
fects. To test the simultaneous marginal homogeneity (SMH) in such clustered
matched-pair multinomial data, three overall tests are proposed. Furthermore,
when the outcome is ordinal, three ordinal statistics which test SMH against
stochastic ordering are proposed.
To evaluate the performance of our methods, we generated a total of 5000
clustered matched-pair data sets, considering number of endpoints = 2; 3; 4 and sample size ranging from 25 to 200. Then our methods are applied to these
5000 datasets and the empirical size and power are compared. The simulation
shows that the Score-type tests perform well with respect to nominal size and
power even with small sample size. For ordinal endpoints, the ordinal statistic
provides uniformly larger power than the one which does not utilize the ordinal
feature. -
