Goodness-of-Fit: An Economic Approach. [PDF]

open access: yes, 2009
Specific functional forms are often used in economic models of distributions; goodness-of-fit measures are used to assess whether a functional form is appropriate in the light of real-world data. Standard approaches use a distance criterion based on the EDF, an aggregation of differences in observed and theoretical cumulative frequencies.

Goodness-of-fit criteria for survival data [PDF]

open access: yes, 2004
The definition of an appropriate measure for goodness-of-fit in case of survival data comparable to R^2 in linear regression is difficult due to censored observations.

Efficient algorithm for testing goodness-of-fit for classification of high dimensional data

open access: yesLietuvos Matematikos Rinkinys, 2009
Let us have a sample satisfying d-dimensional Gaussian mixture model (d is supposed to be large). The problem of classification of the sample is considered. Because of large dimension it is natural to project the sample to k-dimensional (k = 1,  2, . . .)

Random coefficient regressions: parametric goodness of fit tests [PDF]

open access: yes, 1995
Random coefficient regression models have been applied in different fields during recent years and they are a unifying frame for many statistical models.

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

Some Goodness of Fit Tests for Random Sequences

open access: yesLithuanian Journal of Statistics, 2013
In this paper we had made an attempt to incorporate the results from the theory of square Gaussian random variables in order to construct the goodness of fits test for random sequences (time series). We considered two versions of such tests.

Goodness-of-Fit Test for the Bivariate Hermite Distribution

open access: yesAxioms, 2022
This paper studies the goodness of fit test for the bivariate Hermite distribution. Specifically, we propose and study a Cramér–von Mises-type test based on the empirical probability generation function. The bootstrap can be used to consistently estimate

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 ...

Composite Goodness of Fit in Reaeration Coeffcient Modeling [PDF]

open access: yes, 2012
Determination of reaeration coefficient is an important factor in surface water quality modeling as it determines the efficiency of the Streeter-Phelps model used for predicting dissolved oxygen deficit of any stream. This study compared the efficiency

Multivariate goodness-of-fit tests based on kernel density estimators

open access: yesNonlinear Analysis, 2015
The paper is devoted to multivariate goodness-of-fit ests based on kernel density estimators. Both simple and composite null hypotheses are investigated.
