pncs {CopulaInference}

Cdf for non-central squared copula

Description

This function computes the distribution function of the non-central squared copula (ncs) associated a with one-parameter copula with parameter cpar, and parameters a1, a2 >0 .

Usage

pncs(data, family, rotation = 0, par)

Arguments

data

Matrix (x,y) of size n x 2

family

Copula family: "ncs-gaussian", "ncs-clayton", "ncs-frank", "ncs-gumbel", "ncs-joe", "ncs-plackett”.

rotation

Rotation: 0 (default value), 90, 180, or 270.

par

vector of copula parameter and non-centrality parameter a1,a2 >0

Value

cdf

Value of cdf
