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

, 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

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

Journal 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

Journal 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-

Characterizations and Goodness of Fit Tests

Journal 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

Austrian 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.

Nonparametric Bayesian estimation and goodness of fit test [PDF]

, 1985
We first make a review of prior distributions neutral to the right, and then we get the Bayes rule for the survival function S(t) = 1 - F(t), with quadratic loss, with these prior distributions.

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

Mathematics, 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.

Multinomial Goodness-Of-Fit Tests

Journal 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
