Testing Theoretical Hypotheses

Departures from statistical independence are conjoined with an assessment of predictive accuracy in a coefficient of association for nominal-level 2 × 2 contingency tables which is both interpretable as a PRE measure and consistent with research hypotheses of manifold forms. Measurement assumptions and operating characteristics of the measure are delineated; definitional and computational formulae are derived from classical probability theory; comparisons with other relevant statistics are made; and the test of significance is shown to be the traditional chi-square test
