| Abstract | Global and Local Statistical Methods of Analysis for Contingency Tables by Size Effects and Confidence Intervals: This paper presents global and local analyses of a contingency table along the lines of Wilkinson et al. (1999) defining good statistical practices as using effect sizes, confidence intervals and plots instead of tests of significance. On one hand, the global relationship between the two qualitative variables is measured by Cramer's V. A confidence interval may be calculated using the decentred chi-squared distribution by inverting the corresponding significance test. A bootstrap confidence interval is also proposed. On the other hand, Cibois's PEM (percentage of maximum deviation from independence) is a local effect size that can be computed for every cell of the contingency table giving its specific distance from the independence hypothesis. A corresponding confidence interval is calculated by the resampling bootstrap technique. An original plot summarizing these different aspects for the en... |
