Resumen de Discussion about the quality of F-ratio resampling tests for comparing variances

Markus Pauly

• The goal of this paper is to describe the quality of different two-sample bootstrap and permutation tests for comparing variances. It is thereby inter alia shown that studentized resampling versions of the classical F-ratio test are asymptotically effective in a general nonparametric setting. This means that there is asymptotic no loss of power under contiguous alternatives. Moreover it is indicated that these tests are asymptotically consistent for fixed alternatives.
