摘要
We study the first-order bifurcating autoregressive process X-t = phi X-left perpendiculart/2right perpendicular + is an element of(t) with Weibull innovations. Using point process technique, we estimate the model parameter phi and the tail index alpha, in the Weibull distribution and obtain the joint limit distribution of estimators. (C) 2011 Elsevier B.V.
