Testing Copula Hypothesis with Copula Entropy

Testing copula hypothesis is of fundamental importance in the applications of copula theory. In this paper we proposed a copula hypothesis testing with copula entropy. Since copula entropy is a unified theory in probability and therefore testing copula hypothesis based on it can be applied to any types of copula function.

Copula

, 2020
Copulaen er et interessant verktøy i statistikken. Den er brukt i mange forskjellige områder fra finans til klimamodeller. En stor grunn til at copulaen er nyttig er hvordan man kan bruke copulaen til å splitte en bivariat fordeling opp i avhengighets-strukturen og selve marginalfordelingene. Vi vil forklare dette i denne oppgaven.

A Copula-VAR-X Approach for Industrial Production Modelling and Forecasting [PDF]

World economies, and especially European ones, have become strongly interconnected in the last decades and a joint modelling is required. We propose here the use of Copulas to build flexible multivariate distributions, since they allow for a rich ...
