On Entropy Test for Conditionally Heteroscedastic Location-Scale Time Series Models

open access: yesEntropy, 2017
This study considers the goodness of fit test for a class of conditionally heteroscedastic location-scale time series models. For this task, we develop an entropy-type goodness of fit test based on residuals.

Applying the M2 Statistic to Evaluate the Fit of Diagnostic Classification Models in the Presence of Attribute Hierarchies

open access: yesFrontiers in Psychology, 2018
The performance of the limited-information statistic M2 for diagnostic classification models (DCMs) is under-investigated in the current literature. Specifically, the investigations of M2 for specific DCMs rather than general modeling frameworks are ...

New L2-type exponentiality tests [PDF]

open access: yes, 2019
We introduce new consistent and scale-free goodness-of-fit tests for the exponential distribution based on the Puri-Rubin characterization. For the construction of test statistics we employ weighted L2 distance between V-empirical Laplace transforms of ...

Goodness-of-fit test for copulas [PDF]

open access: yes
Copulas are often used in finance to characterize the dependence between assets. However, a choice of the functional form for the copula is an open question in the literature.

On APF Test for Poisson Process with Shift and Scale Parameters

open access: yes, 2018
We propose the goodness of fit test for inhomogeneous Poisson processes with unknown scale and shift parameters. A test statistic of Cramer-von Mises type is proposed and its asymptotic behavior is studied.

Statistical Analysis of Failure Time of the Molar Tooth Using Goodness-of-Fit Technique for Interval Censored Data [PDF]

open access: yesMajallah-i dānishgāh-i ̒ulūm-i pizishkī-i Arāk, 2016
Background: The failure time of permanent tooth is of the form of interval censored since the exact time of tooth decay is not available and it is only known that tooth decay occurs between two consecutive visits.

A Kernel Test of Goodness of Fit [PDF]

open access: yes, 2016
We propose a nonparametric statistical test for goodness-of-fit: given a set of samples, the test determines how likely it is that these were generated from a target density function. The measure of goodness-of-fit is a divergence constructed via Stein's

Finite Sample Corrections for Parameters Estimation and Significance Testing

open access: yesFrontiers in Applied Mathematics and Statistics, 2018
An increasingly important problem in the era of Big Data is fitting data to distributions. However, many stop at visually inspecting the fits or use the coefficient of determination as a measure of the goodness of fit.

Construction of a geographically weighted nonparametric regression model fit test

open access: yesMethodsX
One of the approach of Geographically Weighted Regression (GWR) models is the Geographically Weighted Nonparametric Regression (GWNR) has more parameters than the GWR model.
