ARMAState

class ARMAState(*args)

Last state recorded of an ARMA process.

Parameters:

values : NumericalSample

Last p values of the ARMA(p,q) process of dimension d.

noises : NumericalSample

Last q values of the white noise defining the ARMA(p,q) process of dimension d.

Examples

Define a state of an ARMA(4,2) process of dimension 1:

>>> import openturns as ot
>>> myLastValues = ot.NumericalSample([[0.6], [0.7], [0.3], [0.2]])
>>> myLastNoiseValues = ot.NumericalSample([[1.2], [1.8]])
>>> myARMAState = ot.ARMAState(myLastValues, myLastNoiseValues)
