Permutation p-values for specific-category kappa measure of agreement
Um, Yonghwan;

Asymptotic tests are often not suitable for the analysis of sparse ordered contingency tables as asymptotic p-values may either overestimate or underestimate the true pvalues. In this pater, we describe permutation procedures in which we compute exact or resampling p-values for a weighted specific-category agreement in ordered contingency tables. We use the weighted specific-category kappa proposed by to measure the extent to which two independent raters agree on the specific categories. We carried out comparison studies between exact p-values, resampling p-values and asymptotic p-values using contingency data (real and artificial data sets) and artificial contingency data.
