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 ...

vsgoftest: An R Package for Goodness-of-Fit Testing Based on Kullback-Leibler Divergence [PDF]

open access: yesJournal of Statistical Software, 2020
The R package vsgoftest performs goodness-of-fit (GOF) tests, based on Shannon entropy and Kullback-Leibler divergence, developed by Vasicek (1976) and Song (2002), of various classical families of distributions. The so-called Vasicek-Song (VS) tests are

Remember the Curse of Dimensionality: The Case of Goodness-of-Fit Testing in Arbitrary Dimension [PDF]

open access: yes, 2018
Despite a substantial literature on nonparametric two-sample goodness-of-fit testing in arbitrary dimensions spanning decades, there is no mention there of any curse of dimensionality. Only more recently Ramdas et al.

Goodness-of-fit testing based on a weighted bootstrap: A fast large-sample alternative to the parametric bootstrap [PDF]

open access: yes, 2012
The process comparing the empirical cumulative distribution function of the sample with a parametric estimate of the cumulative distribution function is known as the empirical process with estimated parameters and has been extensively employed in the ...

Goodness-of-fit testing and quadratic functional estimation from indirect observations [PDF]

open access: yes, 2007
We consider the convolution model where i.i.d. random variables $X_i$ having unknown density $f$ are observed with additive i.i.d. noise, independent of the $X$'s. We assume that the density $f$ belongs to either a Sobolev class or a class of supersmooth

Estimation of integrated volatility of volatility with applications to goodness-of-fit testing [PDF]

open access: yes, 2015
In this paper, we are concerned with nonparametric inference on the volatility of volatility process in stochastic volatility models. We construct several estimators for its integrated version in a high-frequency setting, all based on increments of spot ...

Improved kernel estimation of copulas: Weak convergence and goodness-of-fit testing [PDF]

open access: yes, 2009
We reconsider the existing kernel estimators for a copula function, as proposed in Gijbels and Mielniczuk [Comm. Statist. Theory Methods 19 (1990) 445--464], Fermanian, Radulovi\v{c} and Wegkamp [Bernoulli 10 (2004) 847--860] and Chen and Huang [Canad. J.

Adaptive goodness-of-fit testing from indirect observations [PDF]

open access: yes, 2009
International audienceIn a convolution model, we observe random variables whose distribution is the convolution of some unknown density $f$ and some known noise density $g$. We assume that $g$ is polynomially smooth.
