Recursive solution and stability conditions for 2-D least-squares modeling and stabilization problems

Modeling 2-D AR Processes With Various Regions of Support

“…We consider a close-neighbor ordering in the NSHP discussed in [13], [15], [26]. Let g 0 = {(0, 0)}, and…”

“…There exist a lot of difficulties in mathematical and statistical analysis of a noncausal 2-D AR process due to its noncausality. Some least squares (LS) estimators and algorithms are proposed in [13], [14], [15], [16]. An LS estimator of an AR coefficient of a noncausal AR model is statistically inferior.…”
