A New Goodness of Fit Test for Multivariate Normality and Comparative Simulation Study

open access: yesMathematics, 2021
The testing of multivariate normality remains a significant scientific problem. Although it is being extensively researched, it is still unclear how to choose the best test based on the sample size, variance, covariance matrix and others.

An Alternative Measures of Moments Skewness Kurtosis and JB Test of Normality

open access: yesJournal of Statistical Theory and Applications (JSTA), 2021
If we know the statistics of central tendency and dispersion, we still cannot nature a complete design about the distribution. About these measures we should know more information's of skewness and kurtosis, which are enables us to have a design the

The comparison of nonparametric statistical tests for interaction effects in factorial design [PDF]

open access: yesDecision Science Letters, 2019
Correct application of the classical factorial F-test depends on normality and homogeneity of variance assumptions. If these assumptions are violated the type I error rate will be inflated and power of the test will be decreased.

New Graphical Methods and Test Statistics for Testing Composite Normality

open access: yesEconometrics, 2015
Several graphical methods for testing univariate composite normality from an i.i.d. sample are presented. They are endowed with correct simultaneous error bounds and yield size-correct tests.

Empirical Type 1 Error Rate and Power Comparisons of Normality Tests with R

open access: yesCumhuriyet Science Journal, 2018
Normality is one of the main presuppositions instatistical tests. The multiplicity of the normality tests bring out anotherproblem of choosing the appropriate test for researchers.

A Durbin-Watson serial correlation test for ARX processes via excited adaptive tracking [PDF]

open access: yes, 2014
We propose a new statistical test for the residual autocorrelation in ARX adaptive tracking. The introduction of a persistent excitation in the adaptive tracking control allows us to build a bilateral statistical test based on the well-known Durbin ...

Testing Multivariate Normality Based on t-Representative Points

open access: yesAxioms, 2022
Testing multivariate normality is an ever-lasting interest in the goodness-of-fit area since the classical Pearson’s chi-squared test. Among the numerous approaches in the construction of tests for multivariate normality, normal characterization is one ...

Shapiro–Wilk Test with Known Mean

open access: yesRevstat Statistical Journal, 2016
An adaptation of the Shapiro–Wilk W test to the case of normality with a known mean is considered. The table of critical values for different sample sizes and several significance levels is given.
