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 ...

Goodness of fit for stochastic actor-oriented models

open access: yesMethodological Innovations, 2019
We propose a Mahalanobis distance–based Monte Carlo goodness of fit testing procedure for the family of stochastic actor-oriented models for social network evolution.

Goodness-of-Fit Tests on Manifolds [PDF]

open access: yesIEEE Transactions on Information Theory, 2021
We develop a general theory for the goodness-of-fit test to non-linear models. In particular, we assume that the observations are noisy samples of a submanifold defined by a \yao{sufficiently smooth non-linear map}. The observation noise is additive Gaussian.

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

Assessing Goodness of Fit for Verifying Probabilistic Forecasts

open access: yesForecasting, 2021
The verification of probabilistic forecasts in hydro-climatology is integral to their development, use, and adoption. We propose here a means of utilizing goodness of fit measures for verifying the reliability of probabilistic forecasts.

GRASP: A Goodness-of-Fit Test for Classification Learning [PDF]

open access: yesJournal of The Royal Statistical Society Series B-statistical Methodology, 2022
Performance of classifiers is often measured in terms of average accuracy on test data. Despite being a standard measure, average accuracy fails in characterising the fit of the model to the underlying conditional law of labels given the features ...

Monkeying with the Goodness-of-Fit Test

open access: yesJournal of Statistical Software, 2005
The familiar Σ(OBS - EXP) 2/EXP goodness-of-fit measure is commonly used to test whether an observed sequence came from the realization of n independent identically distributed (iid) discrete random variables.

Evaluating the Goodness of Fit of Generalized Nakagami Distribution

open access: yesCumhuriyet Science Journal, 2023
The Generalized Nakagami distribution is a popular distribution in wireless communication. This distribution includes the Nakagami distribution as a special case.

Improving the Hosmer-Lemeshow goodness-of-fit test in large models with replicated Bernoulli trials

open access: yesJournal of Applied Statistics, 2023
The Hosmer-Lemeshow (HL) test is a commonly used global goodness-of-fit (GOF) test that assesses the quality of the overall fit of a logistic regression model.
