M: The Fr<U+00E9>chet--Hoeffding Upper Bound Copula

Description

Compute the Fr<U+00E9>chet--Hoeffding upper bound copula (Nelsen, 2006, p. 11), which is defined as $$\mathbf{M}(u,v) = \mathrm{min}(u,v)\mbox{.}$$ This is the copula of perfect association (comonotonicity, perfectly positive dependence) between \(U\) and \(V\) and is sometimes referred to as the comonotonicity copula. Its opposite is the \(\mathbf{W}(u,v)\) copula (countermonotonicity copula; W), and statistical independence is the \(\mathbf{\Pi}(u,v)\) copula (P).

Usage

M(u, v, ...)

Arguments

u

Nonexceedance probability \(u\) in the \(X\) direction;

v

Nonexceedance probability \(v\) in the \(Y\) direction; and

...

Additional arguments to pass.

Value

Value(s) for the copula are returned.
