A 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...
متن کاملA Permutation Test for Quantile Regression
A drop in dispersion, F -ratio like, permutation test (D) for linear quantile regression estimates (0 ≤ τ ≤ 1) had relative power ≥1 compared to quantile rank score tests (T ) for hypotheses on parameters other than the intercept. Power was compared for combinations of sample sizes (n = 20 − 300) and quantiles (τ = 0.50 − 0.99) where both tests maintained valid Type I error rates in simulations...
متن کاملA Simple Permutation Test for Clusteredness
Hierarchical clustering is a popular method for finding structure in multivariate data, resulting in a binary tree constructed on the particular objects of the study, usually sampling units. The user faces the decision where to cut the binary tree in order to determine the number of clusters to interpret and there are various ad hoc rules for arriving at a decision. A simple permutation test is...
متن کاملA Location-Scale Permutation Test
A permutation test for the location-scale problem is proposed within the nonparametric combination framework. The test is based on the combination of the permutation version of the Student t test and the permutation version of Pan L50 test for scale. Type-one error rate and power of this test are compared with those of Lepage and Cucconi tests. It is shown that the proposed test is preferable u...
متن کاملpermutation approach for adjusted durbin rank test used in balanced incomplete block designs for tied data
durbin's rank test is widely used for testing treatment effects in balanced incomplete block designs (bibds)which have wide applications in sensory analysis. this test is failed for bibds when ties data occur. an adjusted version of durbin rank test for this kind of data is given to solve this problem. chi-square approximation, which is commonly used for this test, is not adequate for small bib...
