DOI: 10.1007/s00184-019-00712-x
Abstract: Various nonparametric test statistics have been proposed for censored data. Two-sample nonparametric testing plays an important role in biometry. While most of two-sample nonparametric tests intend to detect a shift in location or in scale,… read more here.

DOI: 10.1007/s00184-019-00749-y
Abstract: We apply the method of Hankel transforms to develop goodness-of-fit tests for gamma distributions with given shape parameters and unknown rate parameters. We derive the limiting null distribution of the test statistic as an integrated… read more here.

DOI: 10.1007/s11203-018-9176-x
Abstract: The aim of this paper is to introduce a new type of test statistic for simple null hypothesis on one-dimensional ergodic diffusion processes sampled at discrete times. We deal with a quasi-likelihood approach for stochastic… read more here.

DOI: 10.1007/s41237-021-00138-8
Abstract: Although usually taken as a symmetric measure, G is shown to be a directional coefficient of association. The direction in G is not related to rows or columns of the cross-table nor the identity of… read more here.

DOI: 10.1016/j.jspi.2020.11.001
Abstract: Abstract The energy test of multivariate normality is an affine invariant test based on a characterization of equal distributions by energy distance. The test statistic is a degenerate kernel V-statistic, which asymptotically has a sampling… read more here.

DOI: 10.1080/03610926.2016.1242736
Abstract: ABSTRACT In this paper, the problem of whether the left tail and the right tail of a distribution share the same extreme value index (EVI) is addressed and we propose two different test statistics. The… read more here.
