Multiscale image denoising using goodness-of-fit test based on EDF statistics. [PDF]
PLoS ONE, 2019 Two novel image denoising algorithms are proposed which employ goodness of fit (GoF) test at multiple image scales. Proposed methods operate by employing the GoF tests locally on the wavelet coefficients of a noisy image obtained via discrete wavelet ...

A New Parametric Life Distribution with Modified Bagdonavičius–Nikulin Goodness-of-Fit Test for Censored Validation, Properties, Applications, and Different Estimation Methods [PDF]
Entropy, 2020 In this paper, we first study a new two parameter lifetime distribution. This distribution includes “monotone” and “non-monotone” hazard rate functions which are useful in lifetime data analysis and reliability.

Composite Goodness-of-fit Tests with Kernels
J. Mach. Learn. Res., 2021 Model misspecification can create significant challenges for the implementation of probabilistic models, and this has led to development of a range of robust methods which directly account for this issue. However, whether these more involved methods are required will depend on whether the model is really misspecified, and there is a lack of generally ...

Correlation Goodness-of-Fit Test of Mixture of Two Weibull Distributions [PDF]
The Egyptian Statistical Journal, 2006 In this paper, we use the moment of order statistics for testing mixture of two Weibull distrimutions (MTWD) by using correlation-type goodness-of fit test.

A Correlation Type Goodness of Fit Test for the Burr Distribution [PDF]
The Egyptian Statistical Journal, 1996 The Burr family of distributions is widely used in life testing studies. The two common survival or failure-time distributions, the Weibull and the Exponential, are both special cases or limiting cases of the Burr type XII (see Lewis (1981), denoted by ...

An Exhaustive Power Comparison of Normality Tests
Mathematics, 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
Ratio 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 ...

Correlation Coefficient as Goodness-of-Fit Test for the Logistic Distribution [PDF]
The Egyptian Statistical Journal, 1994 Goodness-of-fit tests are used to determine if the data at hand satisfy the distributional assumptions of the statistical model to be used. One of goodness-of-fit tests to use is the correlation coefficient test.

A note on goodness of fit test using moments
Statistica, 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 ...
