Testing Non-Linear Ordinal Responses in L2×K Tables

Leslie Jayasekara, Takashi Yanagawa


In comparative studies responses of two populations are often summarized in stratified 2 ×K tables with ordinal categories. A test, called QEt test, is proposed for testing the homogenuity of the populations against non-linear alternatives in such tables. The asymptotic distributions of proposed test are obtained both under the null and alternative hypothesis. The powers of the QEt test and extended Mantal test are compared by simulation.
