Goodness-of-Fit Tests on Manifolds

چکیده

We develop a general theory for the goodness-of-fit test to non-linear models. In particular, we assume that observations are noisy samples of submanifold defined by sufficiently smooth map. The observation noise is additive Gaussian. Our main result shows “residual” model fit, solving least-square problem, follows (possibly noncentral) χ 2 distribution. parameters distribution related order and dimension problem. further present method select orders sequentially. demonstrate broad application in machine learning signal processing, including determining rank low-rank complex-valued) matrices tensors from noisy, partial, or indirect observations, number sources demixing, potential applications hidden nodes neural networks.

The Comparison Between Goodness of Fit Tests for Copula

‎Copula functions as a model can show the relationship between variables‎. ‎Appropriate copula function for a specific application is a function that shows the dependency between data in a best way‎. ‎Goodness of fit tests theoretically are the best way in selection of copula function‎. ‎Different ways of goodness of fit for copula exist‎. ‎In this paper we will examine the goodness of fit test...

Sobolev Tests of Goodness of Fit of Distributions on Compact Riemannian Manifolds

Classes of coordinate-invariant omnibus goodness-of-fit tests on compact Riemannian manifolds are proposed. The tests are based on Giné's Sobolev tests of uniformity. A condition for consistency is given. The tests are illustrated by an example on the rotation group SO(3). 1. Introduction. Although many tests of goodness of fit are available for distributions on the circle, comparatively little...

An Updated Review of Goodness of Fit Tests Based on Entropy

Different approaches to goodness of fit (GOF) testing are proposed. This survey intends to present the developments on Goodness of Fit based on entropy during the last 50 years, from the very first origins until the most recent advances for different data and models. Goodness of fit tests based on Shannon entropy was started by Vasicek in 1976 and were continued by many authors. In this paper, ...
