cvmgof: an R package for Cramér–von Mises goodness-of-fit tests in regression models

Journal of Statistical Computation and Simulation, 2021
Many goodness-of-fit tests have been developed to assess the different assumptions of a (possibly heteroscedastic) regression model. Most of them are ‘directional’ in that they detect departures from a given assumption of the model.

Goodness-of-Fit Tests on Manifolds [PDF]

IEEE 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.

Conditional Goodness-of-Fit Tests for Discrete Distributions [PDF]

Journal of Statistical Theory and Practice, 2020
In this paper, we address the problem of testing goodness-of-fit for discrete distributions, where we focus on the geometric distribution. We define new likelihood-based goodness-of-fit tests using the beta-geometric distribution and the type I discrete ...

Goodness of fit tests for Rayleigh distribution based on Phi-divergence

Revista Colombiana de Estadística, 2017
In this paper, we develop some goodness of fit tests for Rayleigh distribution based on Phi-divergence. Using Monte Carlo simulation, we compare the power of the proposed tests with some traditional goodness of fit tests including Kolmogorov-Smirnov ...

A comprehensive empirical power comparison of univariate goodness-of-fit tests for the Laplace distribution [PDF]

Journal of Statistical Computation and Simulation, 2020
In this paper, we present the results from an empirical power comparison of 40 goodness-of-fit tests for the univariate Laplace distribution, carried out using Monte Carlo simulations with sample sizes n = 20, 50, 100, 200, significance levels , and 400 ...

Adaptive goodness-of-fit tests based on signed ranks [PDF]

, 2008
Within the nonparametric regression model with unknown regression function $l$ and independent, symmetric errors, a new multiscale signed rank statistic is introduced and a conditional multiple test of the simple hypothesis $l=0$ against a nonparametric ...

Dry months in the agricultural region of Ribeirão Preto, state of São Paulo-Brazil: an study based on the extreme value theory [PDF]

Engenharia Agrícola, 2014
The application of the Extreme Value Theory (EVT) to model the probability of occurrence of extreme low Standardized Precipitation Index (SPI) values leads to an increase of the knowledge related to the occurrence of extreme dry months.

Goodness of Fit Tests and Power Comparisons for Weighted Gamma Distribution

Revstat Statistical Journal, 2016
In this paper, a weighted version of Gamma distribution known as Weighted Gamma (WG) distribution has been considered. Various tests of goodness of fit viz Kolmogorov–Smirnov, Cram´er–von Mises and Anderson–Darling have been applied to this family ...
