ARMAState

class ARMAState(*args)

Last state recorded of an ARMA process.

Parameters:
valuesSample

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

noisesSample

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

Methods

getClassName()

Accessor to the object's name.

getDimension()

Accessor to the dimension of coefficients in the list.

getEpsilon()

Accessor to the last values of the noise defining the ARMA process.

getName()

Accessor to the object's name.

getX()

Accessor to the last values of the ARMA process.

hasName()

Test if the object is named.

setName(name)

Accessor to the object's name.

setXEpsilon(x, epsilon)

Accessor to the last values of the noise defining the ARMA process.

Examples

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

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