非正交因子下APT模型参数估计的渐近性质
ASYMPTOTIC PROPERTIES OF PARAMETRIC ESTIMATION OF APT MODEL UNDER THE NON-ORTHOGONAL FACTOR CONDITION
【摘要】 本文讨论文献[1]中所给APT模型参数估计的渐进性质.当θ∧M存在时,证明了它的强相合性和渐近态性;进而,对无套利场合的APT假设,提出了其LRT和修正的检验方法.
【Abstract】 In this paper, the strong consistency and asymptotic normality of its parametric estimation θ∧M of APT model is given.Further, the LRT and its modified tests for testing the APT hypothesis of no arbi trage opportunity are presented.
