A Novel Goodness-of-Fit Test for Cauchy Distribution

open access: yesJournal of Mathematics, 2023
Recently, several goodness-of-fit tests for Cauchy distribution have been introduced based on Kullback–Leibler divergence and likelihood ratio. It is claimed that these tests are more powerful than the well-known goodness-of-fit tests such as Kolmogorov ...

A Multi-Aspect Permutation Test for Goodness-of-Fit Problems

open access: yesStats, 2022
Parametric techniques commonly rely on specific distributional assumptions. It is therefore fundamental to preliminarily identify the eventual violations of such assumptions. Therefore, appropriate testing procedures are required for this purpose to deal

KSD Aggregated Goodness-Of-Fit Test

open access: yesAdvances in Neural Information Processing Systems 35, 2022
We investigate properties of goodness-of-fit tests based on the Kernel Stein Discrepancy (KSD). We introduce a strategy to construct a test, called KSDAgg, which aggregates multiple tests with different kernels. KSDAgg avoids splitting the data to perform kernel selection (which leads to a loss in test power), and rather maximises the test power over a

An Exhaustive Power Comparison of Normality Tests

open access: yesMathematics, 2021
A goodness-of-fit test is a frequently used modern statistics tool. However, it is still unclear what the most reliable approach is to check assumptions about data set normality. A particular data set (especially with a small number of observations) only

A Simple Goodness-of-Fit Test for Continuous Conditional Distributions

open access: yesRatio Mathematica, 2020
This paper presents a pragmatic specification test for conditional continuous distributions with uncensored data.  We employ Monte Carlo (MC) experiments and the 2011 Medical Expenditure Panel Survey data to examine coverage and power to discern ...

A note on goodness of fit test using moments

open access: yesStatistica, 2007
The purpose of this article is to introduce a general moment-based approach to derive formal goodness of fit tests of a parametric family. We show that, in general, an approximate normal test or a chi-squared test can be derived by exploring the moment ...

Evaluating the Three Methods of Goodness of Fit Test for Frequency Analysis [PDF]

open access: yesJournal of Risk Analysis and Crisis Response (JRACR), 2015
In hydrological statistics, the traditional assessment of goodness of fit test is interested in the testing precision to the sample generated from supposed PDF.

Goodness of Fit Test of an Autocorrelated Time Series Cubic Smoothing Spline Model

open access: yesJournal of Nigerian Society of Physical Sciences, 2021
We investigated the finite properties as well as the goodness of fit test for the cubic smoothing spline selection methods like the Generalized Maximum Likelihood (GML), Generalized Cross-Validation (GCV) and Mallow CP criterion (MCP) estimators for time-

Multinomial Goodness-Of-Fit Tests

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1984
SUMMARY This article investigates the family {I  λ;λ ϵ ℝ} of power divergence statistics for testing the fit of observed frequencies {Xi; i = 1, …, k} to expected frequencies {Ei; i = 1, …, k}. From the definition 2nIλ=2λ(λ+1)∑i=1kXi{(XiEi)λ−1};λ∈ℝ it can easily be seen that Pearson's X  2 (λ = 1), the log likelihood ratio
