Convex Rank Tests and Semigraphoids [PDF]

open access: yes, 2007
Convex rank tests are partitions of the symmetric group which have desirable geometric properties. The statistical tests defined by such partitions involve counting all permutations in the equivalence classes. Each class consists of the linear extensions

Hydraulic Tests of the PZ0 Gear Micropump and the Importance Rank of Its Design and Operating Parameters

open access: yesEnergies, 2022
This article presents the results of hydraulic tests performed for a prototype gear micropump of a new design. The development of modern hydraulic systems is following two directions: the integration of hydraulic and electronic engineering and a ...

Rank tests [PDF]

open access: yesEkonomski Signali, 2017
Rank tests are the most important methods of nonparametric statistics. In the introductory part, there are discussions of parametric and nonparametric metods and as a result of those discussions it is established that the rank tests are one of the most ...

How to use χ2 test correctly——the rank sum tests and the implementation of the SAS software

open access: yesSichuan jingshen weisheng, 2021
The purpose of this article was to introduce the rank sum test and its SAS implementation. The concrete contents included the following three aspects: ①the simple linear rank test of two-sample data, ②the one-way ANOVA rank sum test of the multi-sample ...

Minimum Distance Tests and Estimates Based on Ranks

open access: yesRevstat Statistical Journal, 2020
It is well known that the least squares estimate in classical linear regression model is very sensitive to violation of the assumptions, in particular normality of model errors.

A note on the power of panel conitegration tests - An application to health care expenditure and GDP [PDF]

open access: yes, 2016
This paper enlarges on Gutierrez's (2003) results on the power of panel cointegration tests. By a comparison of power of panel cointegration tests, we show how the choice of most powerful test depends on the values ...

How to use χ2 test correctly——the log-rank test and the implementation of SAS software

open access: yesSichuan jingshen weisheng, 2021
The purpose of this article was to introduce the log-rank test and the SAS implementation. There were many different expression forms for the test statistics of the log-rank tests.

A note on exponentially bounded stopping times of certain one-sample sequential rank order tests

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1985
A simple proof of the exponential boundedness of the stopping time of the one-sample sequential probability ratio tests (SPRT's) is obtained.

Asymptotic Theory for Cointegration Analysis When the Cointegration Rank Is Deficient

open access: yesEconometrics, 2019
We consider cointegration tests in the situation where the cointegration rank is deficient. This situation is of interest in finite sample analysis and in relation to recent work on identification robust cointegration inference.

Nonparametric multivariate rank tests and their unbiasedness

open access: yes, 2012
Although unbiasedness is a basic property of a good test, many tests on vector parameters or scalar parameters against two-sided alternatives are not finite-sample unbiased. This was already noticed by Sugiura [Ann. Inst. Statist. Math.
