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 ...

The sensitivity of chi-squared goodness-of-fit tests to the partitioning of data [PDF]

open access: yes, 2005
In this paper we conduct a Monte Carlo study to determine the power of Pearson’s overall goodness-of-fit test as well as the “Pearson analog” tests (see Anderson (1994)) to detect rejections due to shifts in variance, skewness and kurtosis, as we vary

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

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.

Characterizations and Goodness of Fit Tests

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1982
Summary In this article a systematic approach to providing goodness of fit tests is discussed, for the composite goodness of fit problem of testing that the distribution F of a random sample comes from a parametric family F  o. Characterization procedures are emphasized, and it is shown that, at least for the exponential case, invariant ...

Portmanteau Goodness-of-Fit Test for Asymmetric Power GARCH Models

open access: yesAustrian Journal of Statistics, 2016
The asymptotic distribution of a vector of autocorrelations of squared residuals is derived for a wide class of asymmetric GARCH models. Portmanteau adequacy tests are deduced.

Asymptotic properties of a goodness-of-fit test based on maximum correlations [PDF]

open access: yes, 2008
We study the efficiency properties of the goodness-of-fit test based on the Qn statistic introduced in Fortiana and Grané (2003) using the concepts of Bahadur asymptotic relative efficiency and Bahadur asymptotic optimality.

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.
