pliouv.opt {lcopula}

Internal code for the copula likelihood function of Liouville copulas

Description

The function is used internally for optimization.

Usage

pliouv.opt(theta, data, family, alphavec, MC.approx = TRUE)

Arguments

theta

parameter of the corresponding Archimedean copula

data

sample matrix from a Liouville copula

family

family of the Liouville copula. Either "clayton", "gumbel", "frank", "AMH" or "joe"

alphavec

vector of Dirichlet allocations (must be a vector of integers)

MC.approx

whether to use Monte-Carlo approximation for the inverse survival function (default is TRUE)

Value

value of marginal density
