✦ Synopsis

Likelihood ratio test is considered for testing unimodal dependence as a null hypothesis in a 2 × k ordered contingency table having order restriction on a marginal distribution. The asymptotic least-favorable distribution of the LRT statistic is derived as a convolution of two chi-bar-square distributions. This testing method is illustrated with blood pressure and heart disease data.
