expfunction.nl: Exponent function in the NL model.
Description
The exponent function \(V\) for a max-stable variable \(M\) is such that \(P(M<x) = exp(-V(x))\)
Usage
expfunction.nl(par = c(0.3, 0.4, 0.5, 0.6), x = 10 * rep(1, 3))
Value
the value of \(V(x)\) for \(x=thres\).
Arguments
- par
The parameter for the NL distribution,
respectively of length two or four.
- x
A vector of three extended positive real numbers
