hwwntest (version 1.3.2)

d00.test: Test for white noise based on the coarsest scale Haar wavelet coefficient of the spectrum.

Description

Computes the coarsest scale Haar wavelet coefficient of the periodogram but directly using a formula based on a particular linear combination of autocorrelation coefficients. Then performs a hypothesis test by comparing the test statistic to a standard normal distribution.

Usage

d00.test(x)

Value

An object of class htest containing the following components.

statistic

The test statistic

p.value

The p-value of the test

method

A test string indicating the method

Arguments

x

The time series you want to test, of arbitrary length.
