Asymmetric Stable Distributed Security Returns
研究发现证券收益率分布存在显著正偏态,挑战了对称稳定分布优于高斯分布的传统结论,促使重新审视稳定分布参数(尤其是特征指数)的估计。
Abstract Included in the canon of applied statistics and finance is the conclusion that the symmetric stable paradigm better characterizes security return distributions than the Gaussian. The focus of the present effort is on the symmetry of the distributions. Evidence is provided that indicates that securities tend to display substantial positive skewness, motivating a reexamination of past attempts to measure the parameters of the stable distribution, particularly the characteristic exponent.
