This proposed test statistic is a generalization of Lin and Chen's statistic (2005 Lin , K. C. , Chen , Y. J. ( 2005 ).

) to ordinal response data. The extension of logistic regression models for binary responses to ordinal responses is usually involved by modeling cumulative logits. The expectation and variance of the proposed test statistic are derived, and t
