Copulas and Self-affine Functions
2013We characterize self-affine functions whose graphs are the support of a copula using the fact that the functions defined on the unit interval whose graphs support a copula are those that are Lebesgue-measure-preserving. This result allows the computation of the Hausdorff, packing, and box-counting dimensions.

Copula functions are a group of multivariate distribution functions that join the marginal distribution of multiple variables. They have been used in different fields of science and engineering during the past decades. The main advantage of copulas over other multivariate distribution functions is their flexible structure in choosing marginal ...

The copula function of pronouns
Lingua, 1983Abstract This paper presents evidence from Egyptian Arabic to show that in the absence of a copula from a language, the language may use pronouns to perform copula functions. The evidence is based on the behavior of pronouns with respect to Negative Placement and their use in equational sentences.

Binary copulas as aggregation functions
2014 IEEE 15th International Symposium on Computational Intelligence and Informatics (CINTI), 2014We present binary copulas or 2-copulas (copulas, shortly) as important aggregation function. Since generally copulas are non-associative operation we restrict on binary case, which is mostly used in the practice. After giving some introductory part on general aggregation functions we restrict on specific properties of copulas.

Copula Functions in Model Based Clustering
2006Model based clustering is common approach used in cluster analysis. Here each cluster is characterized by some kind of model, for example — multivariate distribution, regression, principal component etc. One of the most well known approaches in model based clustering is the one proposed by Banfield and Raftery (1993), where each class is described by ...
