deltarhodcca.test: Statistical test for Statistical test for Delta RHODCCA cross-correlation coefficient.

Description

This function performs the statistical test for Delta RHODCCA cross-correlation coefficient from two univariate ARFIMA process.

Usage

deltarhodcca.test(x, y, k, m, nu, rep)

Arguments

x

A vector containing univariate time series.

y

A vector containing univariate time series.

k

An integer value indicating the boundary of the division \((N/k)\). The smallest value of \(k\) is \(4\).

m

an integer value or a vector of integer values indicating the size of the window for the polinomial fit.

nu

An integer value. See the DCCA package.

rep

An integer value indicating the number of repetitions.

Value

An list containing "timescale", "mean", "sd", "rho_before", "rho_affter", "deltarho", "CI_0.90", "CI_0.95", "CI_0.99".

Details

This function include following measures: timescale, rho_before, rho_affter, deltarho
