LS2Wstat (version 2.1-5)

avespecvar: A test statistic for spatial stationarity.

Description

Calculates a test statistic for a test of stationarity based on the local wavelet spectrum.

Usage

avespecvar(spectrum)

Value

statistic

The value of the test statistic for the given spectrum.

Arguments

spectrum

A local wavelet spectrum estimate, i.e. a cddews object.

Author

Sarah L. Taylor

Details

The test statistic given by Taylor et al. (2014) for a test for stationarity is computed for use in the boostrap testing procedure (TOS2D).
