numerical_conditional_cop {cylcop}

Numerically Calculate the Conditional Copula

Description

Numerically Calculate the Conditional Copula

Usage

numerical_conditional_cop(u, copula, cond_on)

Arguments

u

matrix or vector of numeric values in I^2, containing as first column the circular (periodic) and as second the linear dimension.

copula

R object of class 'cyl_copula' or 'Copula' (package 'copula', only 2-dimensional).

cond_on

column number of u on which the copula is conditioned. E.g. if cond_on = 2, the function calculates for each element in the first column of u the copula conditional on the element in the second column.

Value

A vector containing the values of the distribution of the copula at u[,-cond_on] conditional on the values of u[,cond_on].
