A Further Enhanced M-estimator for the K-distribution Shape Parameter
-
摘要: K分布形状参数的M估计器是一种估计精度比较高的估计器，2005年由郝程鹏提出，2007年得到了进一步的改进。该文对2007年的改进的M估计器进行了进一步的改进，省去了其中的一些中间环节，仿真实验证明，该文方法显著提高了估计器的精度与效率。Abstract: M-estimator is a new estimator presented by Hao Cheng-peng in 2005, which possesses higher accuracy in the estimation of shape parameter of K-distribution and is enhanced in 2007. In this paper, a further enhanced M-estimator is proposed based on the enhanced M-estimator in 2007, in which some original middle procedures are omitted. The simulation results show that the estimation accuracy and efficiency both increase dramatically.
