 Abstract
In this paper we show that the peak of the type I error rate of the Oochran-Armitage trend test could be greater than the nominal level when contingency tables obtained from two multinomial distributions are extremely unbalanced. This result justifies the use of the exact Cochran-Armitage trend test in extremely unbalanced contingency tables.
