AR: Simulation of an AR(p) surrogate for a given time series x

Description Usage Arguments Details Value Author(s) See Also

View source: R/AR.R


It simulates an AR(p) surrogate for the 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.

Simulation is subject to coefficient estimates referring to the given AR order.


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



the given time series


a list containing an assignment of (the only) parameter value to AR. Default: NULL.

Default includes:

AR = list(...), a list containing one single element:

p : AR order.
Default: 1.


Basics of model estimation and simulation are provided by application of the R functions pcf and arima.sim.


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