statsmodels.tsa.kalmanf.kalmanfilter.KalmanFilter.R

classmethod KalmanFilter.R(params, r, k, q, p)

The coefficient matrix for the state vector in the observation equation.

Its dimension is r+k x 1.

Parameters:

r : int

In the context of the ARMA model r is max(p,q+1) where p is the AR order and q is the MA order.

k : int

The number of exogenous variables in the ARMA model, including the constant if appropriate.

q : int

The MA order in an ARMA model.

p : int

The AR order in an ARMA model.
