Simulation of a surrogate for a given time series x by Fourier randomization
It simulates a surrogate with similar Fourier spectrum for a given time series x analyzed
by wavelet transformation using either function analyze.wavelet
or function analyze.coherency
.
A set of surrogates is used for significance assessment to test the hypothesis of equal periodic components.
This code has been developed by Huidong Tian (archived R package WaveletCo
).
FourierRand(x)
x |
the given time series |
A surrogate series for x is returned which has the same length and a similar Fourier spectrum.
