The copula function of pronouns

Lingua, 1983
Abstract 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), 2014
We 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

2006
Model 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 ...

Copula Function and C-Volume

2021
This chapter is devoted to a short review of the basic concepts of the theory of dependence functions or copula functions, as they are more usually called. In particular our objective is to define the volume of a copula function: this is one of the basic ingredients of the aggregation algorithm that will be discussed in Part II.

Archimedean Utility Copulas with Polynomial Generating Functions

Decision Analysis, 2019
Archimedean utility copulas comprise the general class of multiattribute utility functions that have additive ordinal preferences and are strictly increasing with each argument for at least one reference value of the complementary attributes. The construction of an Archimedean utility copula requires an assessment of an individual utility function for

Extreme distribution functions of copulas

Kybernetika, 2008
Summary: We study some properties of the distribution function of the random variable \(C(X,Y)\) when the copula of the random pair \((X,Y)\) is \(M\) (respectively, \(W\)) -- the copula for which each of \(X\) and \(Y\) is almost surely an increasing (respectively, decreasing) function of the other -- and \(C\) is any copula.

THE JAPANESE COPULA: FORMS AND FUNCTIONS

Studies in Second Language Acquisition, 2004
THE JAPANESE COPULA: FORMS AND FUNCTIONS. Tomiko Narahara. New York: Palgrave Macmillan, 2002. Pp. x + 210. $55.00 cloth. This book examines the Japanese copula, da and datta, which occurs with predicative nominals and adjectival nominals. Narahara's primary contribution is to challenge the common assumption that the Japanese copula is a tense ...
