Description Usage Arguments Methods References
The h^{-1} function represents the inverse of the h function with respect to its first argument. It should be defined for every copula used in a pair-copula construction (or it will be evaluated numerically).

signature(copula = "copula")
Default definition of the h^{-1} function for a bivariate copula.
This method is used if no particular definition is given for a copula.
The inverse is calculated numerically using the uniroot
function.
signature(copula = "indepCopula")
The h^{-1} function of the Independence copula.
signature(copula = "normalCopula")
The h^{-1} function of the normal copula.
signature(copula = "tCopula")
The h^{-1} function of the t copula.
signature(copula = "claytonCopula")
The h^{-1} function of the Clayton copula.
signature(copula = "frankCopula")
The h^{-1} function of the Frank copula.
