`analyze.wavelet`

or function `analyze.coherency`

. A set of surrogates is used for significance assessment to test the hypothesis of equal periodic components.Simulation is subject to coefficient estimates referring to the given AR order.

`AR(x, params = list(AR = list(p = 1)))`

x

the given time series

params

a list containing an assignment of (the only) parameter value to AR. Default: NULL.
Default includes:
AR = list(p=1), where:
rlll {
p : AR ord

- A surrogate series for x is returned which has the same length and properties according to estimates resulting from the given AR order.
