An introduction to copulas — Copulae 0.7.7 documentation
网页A simple explanation of Copulas ¶. From Wikipedia ’s definition: A copula is a multivariate cumulative distribution function for which the marginal probability distribution of each variable is uniform on the interval [0, 1]. Copulas are used to describe the dependence between random variables.

Copulae: An overview and recent developments - Größer - 2022
网页2021年4月3日 · Copulae are special forms of bivariate and multivariate functions and they are an elegant way to express those multivariate distributions. Sklar (1959) showed that a copula exists for any multivariate distribution, such that the joint distribution equals the copula applied to the marginal distributions.
Copula系列（一）-什么是Copula函数 - 知乎 - 知乎专栏
网页copula这个单词来自于拉丁语，意思是“连接”。 最早是由Sklar在1959年提出的，即Sklar定理： 以二元为例，若 H (x,y) 是一个具有连续边缘分布的 F (x) 与 G (y) 的二元联合分布函数，那么存在唯一的Copula函数 C ，使得 H (x,y)=C (F (x),G (y)) 。 反之，如果 C 是一个copula函数，而 F 和 G 是两个任意的概率分布函数，那么由上式定义的 H 函数一定是一个联合分布函数，且对应的边缘分布刚好就是 F 和 G 。

Copula (statistics) - Wikipedia
网页Copula (statistics) In probability theory and statistics, a copula is a multivariate cumulative distribution function for which the marginal probability distribution of each variable is uniform on the interval [0, 1]. Copulas are used to describe/model the dependence (inter-correlation) between random variables. [1]
Copulae: : An overview and recent developments - ACM Digital …
网页2022年5月12日 · This work gives an overview of copula theory and it also summarizes the latest results. This article recalls the basic definition, the most important cases of bivariate copulae, and it then proceeds to a sketch of how multivariate copulae are developed both from bivariate copulae and from scratch.
Copulae in High Dimensions: An Introduction | SpringerLink
网页2017年8月4日 · In this section, we discuss three copula classes namely simple, elliptical and Archimedean copulae. Simplest Copulae. To form basic intuition for copula functions, we first study some extreme special cases, like stochastically independent, perfect positive or negative dependent random variables.
