The Fréchet–Hoeffding Upper-Bound Copula

Description

Compute the Fréchet–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.
