基于EM算法的稳定分布统计推断

Statistical Inference for Stable Distribution Using EM algorithm

Mahdi Teimouri

摘要:

$α$类-稳定分布,在经济学、电信学、生物学、应用物理学和理论物理学中有广泛的应用。这是由于它同时具有偏态和重尾的事实。由于$α$ -稳定分布的密度函数是一个封闭的表达式,因此寻找其参数的有效估计已经引起了大量的关注。本文给出了$α$ -稳定分布参数的极大似然估计的EM算法。所提出的EM算法的性能证明通过比较研究,在存在其他知名的竞争对手和分析三组真实数据。

英文摘要:

The class of $α$-stable distributions with a wide range of applications in economics, telecommunications, biology, applied, and theoretical physics. This is due to the fact that it possesses both the skewness and heavy tails. Since $α$-stable distribution suffers from a closed-form expression for density function, finding efficient estimators for its parameters has attracted a great deal of attention in the literature. Here, we propose some EM algorithm to estimate the maximum likelihood estimators of the parameters of $α$-stable distribution. The performance of the proposed EM algorithm is demonstrated via comparison study in the presence of other well-known competitors and analyzing three sets of real data.
