Analysis of singly ordered two-way contingency tables
Summary: Pearson's statistic is investigated for nominal-ordinal two-way contingency tables in which we wish to test for identical rows. The statistic is expressed as a sum, the first summand of which is a statistic given by \textit{F. Yates} [Biometrika, Cambridge 35, 176-181 (1948; Zbl 0030.31402)], and examines location effects for the nominal category. The second and subsequent summands reflect the corresponding moments: for example, dispersion, skewness, kurtosis etc. The summands are shown to be weakly optimal in that they are score statistics.
