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.
