Copula and semicopula transforms [PDF]

open access: goldInternational Journal of Mathematics and Mathematical Sciences, 2005
We characterize the transformation, defined for every copula C, by Ch(x, y) : = h[−1](C(h(x), h(y))), where x and y belong to [0, 1] and h is a strictly increasing and continuous function on [0, 1]. We study this transformation also in the class of quasi‐copulas and semicopulas.

Counting semicopulas on finite structures [PDF]

open access: greenFuzzy Sets and Systems, 2022
Semicopulas are the operators chosen to model conjunction in the fuzzy/many-valued logics. In fact, a special kind of semicopula, called t-norm, is widely used in many applications of logic to engineering, computer science and fuzzy systems.

Coherence and avoidance of sure loss for standardized functions and semicopulas [PDF]

open access: greenInternational Journal of Approximate Reasoning, 2023
We discuss avoidance of sure loss and coherence results for semicopulas and standardized functions, i.e., for grounded, 1-increasing functions with value $1$ at $(1,1,\ldots, 1)$. We characterize the existence of a $k$-increasing $n$-variate function $C$

The study on semicopula based implications [PDF]

open access: bronzeKybernetika, 2020
\textit{M. Baczyński} et al. [Fuzzy Sets Syst. 323, 138--151 (2017; Zbl 1394.03042)] were the first authors to construct implications combining a given a priori fuzzy implication and a semicopula. Here, the relationship between the a priori fuzzy implication and the semicopula based implication are pointed out.

Fuzzy implications based on semicopulas

open access: closedAsian Journal of Probability and Statistics, 2016
In this paper we have introduced semicopula function by using Rüschendorf method, semicopula  which is related to correlation between one or more random variables and this way is more flexible than traditional correlation approaches and dependency among variables.

Semicopulas : Characterizations and applicability [PDF]

open access: green, 2006
Summary: We characterize some bivariate semicopulas and, among them, the semicopulas satisfying a Lipschitz condition. In particular, the characterization of harmonic semicopulas allows us to introduce a new concept of depedence between two random variables.

Semicopulae [PDF]

open access: yes, 2005
We define the notion of semicopula, a concept that has already appeared in the statistical literature and study the properties of semicopulas and the connexion of this notion with those of copula, quasi-copula, t ...
