Monkeying with the Goodness-of-Fit Test [PDF]

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.

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.

Gradient-Free Kernel Conditional Stein Discrepancy goodness of fit testing

open access: yesMachine Learning with Applications, 2023
In this study, we propose a gradient-free statistical goodness-of-fit test for determining if a joint sample (xi,yi)is drawn from p(y|x)πxfor some density πxgiven a conditional distribution.

Asymptotic Pitman's Relative Efficiency

open access: yesStatistica, 2017
Pitman efficiency is the oldest known efficiency.  Most of the known results for computing the Pitman efficiency take the form of bounds.  Based on some recent developments due to the authors and some calculus of variations, we develop tools for ...

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, . . .)
