Webrandom matrices appear in a variety of di erent models in statistical mechanics. A promi-nent example is the planar random growth models which belong to Kardar-Parisi-Zhang … WebTheorem 1 shows that, when Pl = P2 = P3 = 2, the range of p for the AR(1) is [-1, 1], whereas for the MA(1) the range is [-4,4]. This is analogous to range restrictions on the MA(1) correlation parameter for normal correlation matrices.
