This paper proposes a distribution-free test for the two-sample scale problem in ranked set samples. The proposed test assumes that the distribution functions of the populations have a common quantile ...

A non-parametric test for the bivariate c-sample problem is proposed. The test is an extension of a bivariate two-sample test given by Mardia (1967) and possesses various desirable properties. We ...

Nonparametric tests robustly compare skewed or ranked data. Figure 1: A sample can be easily tested against a reference value using the sign test without any assumptions about the population ...
