Goodness-of-Fit Tests for COM-Poisson Distribution Using Stein's Characterization

open access: yesAustrian Journal of Statistics
A crucial part of data analysis is to assess the adequacy of the fit of the probability models used, and such assessment is generally made using the goodness-of-fit tests.

Assessing Conformance with Benford's Law: Goodness-Of-Fit Tests and Simultaneous Confidence Intervals. [PDF]

open access: yesPLoS ONE, 2016
Benford's Law is a probability distribution for the first significant digits of numbers, for example, the first significant digits of the numbers 871 and 0.22 are 8 and 2 respectively.

Goodness-of-fit tests for the Compound Rayleigh distribution with application to real data [PDF]

open access: yesHeliyon, 2019
An important problem in statistics is to obtain information about the form of the population from which the sample is drawn. Goodness of fit (GOF) tests is employed to determine how well the observed sample data “fits” some proposed model. The well known

Goodness-of-Fit Tests for Copulas of Multivariate Time Series

open access: yesEconometrics, 2017
In this paper, we study the asymptotic behavior of the sequential empirical process and the sequential empirical copula process, both constructed from residuals of multivariate stochastic volatility models. Applications for the detection of structural

Goodness-of-fit tests and model diagnostics for negative binomial regression of RNA sequencing data. [PDF]

open access: yesPLoS ONE, 2015
This work is about assessing model adequacy for negative binomial (NB) regression, particularly (1) assessing the adequacy of the NB assumption, and (2) assessing the appropriateness of models for NB dispersion parameters.

Goodness--of--fit tests for stochastic frontier models based on the characteristic function [PDF]

open access: yesJournal of Productivity Analysis, 2022
We consider goodness–of–fit tests for the distribution of the composed error in Stochastic Frontier Models. The proposed test statistic utilizes the characteristic function of the composed error term, and is formulated as a weighted integral of properly ...

Goodness–of–Fit Tests for Bivariate Time Series of Counts

open access: yesEconometrics, 2021
This article considers goodness-of-fit tests for bivariate INAR and bivariate Poisson autoregression models. The test statistics are based on an L2-type distance between two estimators of the probability generating function of the observations: one being

Two-sample goodness-of-fit tests on the flat torus based on Wasserstein distance and their relevance to structural biology [PDF]

open access: yesElectronic Journal of Statistics, 2021
This work is motivated by the study of local protein structure, which is defined by two variable dihedral angles that take values from probability distributions on the flat torus.
