cyl_quadsec {cylcop}

Construction of 'cyl_quadsec' Objects

Description

Constructs a circular-linear copula with cubic sections of class 'cyl_quadsec'.

Usage

cyl_quadsec(a = 1/(2 * pi))

Arguments

a

numeric value of the parameter of the copula. It must be in [- 1 / (2 \pi)), 1 / (2 \pi))].

Value

An R object of class 'cyl_quadsec'.
