Abstract :
The two-dimensional autoregressive modelling problem is attempted using a combination of the Yule-Walker system of equations and the Yule-Walker system of equations in the third-order statistical domain. A novel weighting scheme that relates the contribution of the two systems is proposed and some simulations results are provided to verify the improved estimations.
