چکیده

Abstract Correlated binary data are prevalent in a wide range of scientific disciplines, including healthcare and medicine. The generalized estimating equations (GEEs) the multivariate probit (MP) model two popular methods for analyzing such data. However, both have some significant drawbacks. GEEs may not an underlying likelihood MP fail to generate distribution with specified marginals bivariate correlations. In this paper, we study distributions that based on D-vine pair-copula models as superior alternative these methods. We elucidate construction three dimensions numerical examples. For higher dimensions, provide method constructing multidimensional equicorrelated correlation matrix. present real-life analysis illustrate application our results.

Pair-copula constructions of multivariate copulas

The famous Sklar’s theorem (see [54]) allows to build multivariate distributions using a copula and marginal distributions. For the basic theory on copulas see the first chapter ([14]) or the books on copulas by Joe ([32]) and Nelson ([51]). Much emphasis has been put on the bivariate case and in [32] and [51] many examples of bivariate copula families are given. However the class of multivaria...

Estimating Multivariate Discrete Distributions Using Bernstein Copulas

Measuring the dependence between random variables is one of the most fundamental problems in statistics, and therefore, determining the joint distribution of the relevant variables is crucial. Copulas have recently become an important tool for properly inferring the joint distribution of the variables of interest. Although many studies have addressed the case of continuous variables, few studie...

Bayesian inference for multivariate copulas using pair-copula constructions

This article provides a Bayesian analysis of pair-copula constructions (Aas et al., 2007 Insurance Math. Econom.) for modeling multivariate dependence structures. These constructions are based on bivariate t−copulas as building blocks and can model the nature of extremal events in bivariate margins individually. According to recent empirical studies (Fischer et al. (2007) and Berg and Aas (2007...

Modeling Multivariate Distributions Using Copulas: Applications in Marketing

In this research we introduce a new class of multivariate probability models to the marketing literature. Known as “copula models”, they have a number of attractive features. First, they permit the combination of any univariate marginal distributions that need not come from the same distributional family. Second, a particular class of copula models, called “elliptical copula”, have the property...

Generating Spatial Correlated Binary Data Through a Copulas Method

Simulating spatial correlated binary data is very important on many cases, but it is not easily to accomplish, as there are restrictions on the parameters of Bernoulli variables. This paper develops a copulas method to generate spatial correlated binary data. The spatial binary data generated by this method has an inverse spatial pattern comparing with the latent Gaussian random field data, how...
