mult.loc: Wavelet-based Testing and Locating for Variance Change Points

Description Usage Arguments Details Value Author(s) References See Also

Description

This is the major subroutine for testing.hov, providing the workhorse algorithm to recursively test and locate multiple variance changes in so-called long memory processes.

Usage

1
mult.loc(dwt.list, modwt.list, wf, level, min.coef, debug)

Arguments

dwt.list

List of wavelet vector coefficients from the dwt.

modwt.list

List of wavelet vector coefficients from the modwt.

wf

Name of the wavelet filter to use in the decomposition.

level

Specifies the depth of the decomposition.

min.coef

Minimum number of wavelet coefficients for testing purposes.

debug

Boolean variable: if set to TRUE, actions taken by the algorithm are printed to the screen.

Details

For details see Section 9.6 of Percival and Walden (2000) or Section 7.3 in Gencay, Selcuk and Whitcher (2001).

Value

Matrix.
