Goodness-of-fit testing for meta-analysis of rare binary events [PDF]

open access: yesScientific Reports, 2023
Random-effects (RE) meta-analysis is a crucial approach for combining results from multiple independent studies that exhibit heterogeneity. Recently, two frequentist goodness-of-fit (GOF) tests were proposed to assess the fit of RE model.

Nonparametric goodness‐of‐fit testing for parametric covariate models in pharmacometric analyses [PDF]

open access: yesCPT: Pharmacometrics & Systems Pharmacology, 2021
The characterization of covariate effects on model parameters is a crucial step during pharmacokinetic/pharmacodynamic analyses. Although covariate selection criteria have been studied extensively, the choice of the functional relationship between ...

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.

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.

Testing EBUCA Class of Life Distribution Based on Goodness of Fit Approach [PDF]

open access: yesThe Egyptian Statistical Journal, 2007
Test statistics for testing exponentiality against exponential better (worse) than used in convex average EBUCA is proposed in non-censored and censored cases by using goodness of fit approach. Selected critical values are tabulated.

Testing EBU_mgf Class of Life Distributions based on Goodness of Fit approach [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2016
Based on the goodness of fit approach, a new test is presented for testing exponentiality against "exponential Better than Used in moment generating function ordering class" (EBUmgf). The critical values and the powers of this test are calculated.

Testing for goodness rather than lack of fit of continuous probability distributions.

open access: yesPLoS ONE, 2021
The vast majority of testing procedures presented in the literature as goodness-of-fit tests fail to accomplish what the term is promising. Actually, a significant result of such a test indicates that the true distribution underlying the data differs ...

Score-Based Hypothesis Testing for Unnormalized Models

open access: yesIEEE Access, 2022
Unnormalized statistical models play an important role in machine learning, statistics, and signal processing. In this paper, we derive a new hypothesis testing procedure for unnormalized models. Our approach is motivated by the success of score matching

KSD Aggregated Goodness-Of-Fit Test

open access: yesAdvances in Neural Information Processing Systems 35, 2022
We investigate properties of goodness-of-fit tests based on the Kernel Stein Discrepancy (KSD). We introduce a strategy to construct a test, called KSDAgg, which aggregates multiple tests with different kernels. KSDAgg avoids splitting the data to perform kernel selection (which leads to a loss in test power), and rather maximises the test power over a
