recommendations! Published in 2019 at "Metrika"

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.

recommendations! Published in 2021 at "Journal of Statistical Planning and Inference"

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.

DOI: 10.3390/e24101444

Abstract: This paper introduces and studies a new generalization of cumulative past extropy called weighted cumulative past extropy (WCPJ) for continuous random variables. We explore the following: if the WCPJs of the last order statistic are… read more here.

DOI: 10.3390/sym14020291

Abstract: An extension of the D2 test statistic to test the equality of mean for high-dimensional and k-th order array-variate data using k-self similar compound symmetry (k-SSCS) covariance structure is derived. The k-th order data appear… read more here.

recommendations! Published in 2022 at "Behavior Research Methods"

DOI: 10.3758/s13428-021-01729-9

Abstract: In structural equation modeling, several corrections to the likelihood-ratio model test statistic have been developed to counter the effects of non-normal data. Previous robustness studies investigating the performance of these corrections typically induced non-normality in… read more here.
