On Small Sample Properties of Permutation Tests: a Significance Test for Regression Models*
In this paper, we consider a nonparametric permutation test on the correlation coefficient, which is applied to a significance test on regression coefficients. Because the permutation test is very computerintensive, there are few studies on small-sample properties, although we have numerous studies on asymptotic properties with regard to various aspects. In this paper, we aim to compare the per...
متن کاملthe relationship between eq, iq and test format: a study on test fairness
the major aim of this study was to investigate the relationship between iq, eq and test format in the light of test fairness considerations. this study took this relationship into account to see if people with different eq and iq performed differently on different test formats. to this end, 90 advanced learners of english form college of ferdowsi university of mashhad were chosen. they were ask...
15 صفحه اولA permutation test motivated by microarray data analysis
We introduce a nonparametric test intended for large-scale simultaneous inference in situations where the utility of distribution-free tests is limited because of their discrete nature. Such situations are frequently dealt with in microarray analysis where the number of tests is much larger than the sample size. The proposed test statistic is based on a certain distance between the distribution...
متن کاملPermutation Complexity Bound on Out-Sample Error
Assume a standard setting with data D = {(xi, yi)}i=1, where (xi, yi) are sampled iid from the joint distribution p(x, y) on Rd×{±1}. Let H = {h : R 7→ {±1}} be a learning model which produces a hypothesis g ∈ H when given D (we use g for the hypothesis returned by the learning algorithm and h for a generic hypothesis in H). We assume the 0-1 loss, so the in-sample error is ein(h) = 1 2n ∑n i=1...
متن کاملA Permutation Test for Matching
We consider a permutation method for testing whether observations given in their natural pairing exhibits an unusual level of similarity in situations where any two observations may be similar at some unknown baseline level. Under a null hypotheses where there is no distinguished pairing of the observations, a normal approximation, with explicit bounds and rates, is presented for determining ap...
