phi, phi.inv {HAC} | R Documentation |
Generator function
Description
The Archimedean generator function and its inverse.
Usage
phi(x, theta, type)
phi.inv(x, theta, type)
Arguments
x |
a scalar, vector or matrix at which the function is evaluated. The support of the functions has to be taken into account, i.e. |
theta |
the feasible copula parameter, i.e. |
type |
select between the following integer numbers for specifying the
|
Examples
x = runif(100, min = 0, max = 100)
phi(x, theta = 1.2, type = 1)
# do not run
# phi(x, theta = 0.8, type = 1)
# In phi(x, theta = 0.8, type = 1) : theta >= 1 is required.
