LS2Wstat-package: Stationarity testing for locally stationary wavelet fields

LS2Wstat-packageR Documentation

Stationarity testing for locally stationary wavelet fields


This package contains functions for testing for stationarity within images, specifically locally stationary wavelet (LS2W) fields. In addition the package contains functions for implementing quadtree image decompositions, as well as code for simulating LS2W processes for a given spectral structure.
