Title: Simultaneous Bootstrap Confidence Intervals for Scale Difference Using Deviances
Author(s): Scott Richter* and Melinda McCann
Companies: and Oklahoma State University
Keywords: confidence interval; scale parameter; bootstrap

Bootstrap confidence intervals based on medians are examined for pairwise comparison of scale. Methods that have been found in the literature to be effective for comparing scale for two groups are extended to the case of all pairwise comparisons, using the Tukey-type adjustment of Richter & McCann (2007) to guarantee strong Type I error rate control. Power and Type I error rate estimates are computed and compared to other methods based on deviances using simulated data.

Authors who are presenting talks have a * after their name.
