classmethod KalmanFilter.T(params, r, k, p)[source]

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

Its dimension is r+k x r+k.

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.

p : int

The AR coefficient in an ARMA model.
