In this paper, a general class of non parametric tests is proposed for the two-sample scale
problem. Testing of the scale parameter is very useful in real-life situations commonly faced …

A new class of distribution-free tests for the two-sample location problem is proposed. The
tests are based on two-sample U-statistics. This class basically generalizes the tests …

A new test based on linear combinations of U-statistics for testing homogeneity of location
parameters against ordered alternatives is proposed. Asymptotic distribution of the test …

Abstract Let X ij j= 1, 2,…, ni. be a random sample of size ni. from an absolutely continuous
distribution with distributionfunction F (×/σ i.), with mean O; i= 1, 2,…, k. The problem …

Let Xi 1, Xi 2… Xi n, i= 1, 2,…, K independent random samples of size ni from absolutely
continuous distributions with distribution functions Fi. We assume that these distribution …

This paper introduces a new class of distribution-free tests for testing the homogeneity of
several location parameters against ordered alternatives. The proposed class of test …

Three nonparametric tests for several sample scale problem against umbrella alternative,
when the peak of the umbrella is known, are proposed. The proposed statistics have the …

Two classes of distribution-free tests for homogeneity of several populations agaist
stochastic ordering are proposed. One class of tests is shown to perform better for …

A new class of distribution-free tests for the k-sample location problem based on the linear
combination of two-sample U-statistics proposed by Ozturk (2001) is proposed. Asymptotic …

A nonparametric test for the several-sample scale problem is proposed, based on ranked-
set data. The proposed test has the advantage of not requiring the several distribution …
