Local versus global association for bivariate ordered responses
Applied Mathematics Division, D.S.I.R. Auckland, New Zealand
Local and global parameters modelling association are examined for contingency tables with both margins ordered responses. Local association parameters are cross-ratios of 2 x 2 subtables of adjacent cell probabilities: global association parameters are cross-ratios of quadrant probabilities. The interpretation and various properties of these measures of association are compared and illustrated.
