泊松分布参数的稳健估计
Robust Estimation of Parameter in Poisson Distribution
摘要
Abstract
This paper, the asymmetrical distribution of the Poisson distribution as an objective, discussed the estimation method of robust parameter. Author truncated likelihood estimation, combining Cizek's work, proposed a robust estimation method applying to Poisson distribution parameters. It avoided the hassle of pre-selected cutoff ratio, and gave their information through the data at an average maximum likelihood ratio criterion optimal truncation. In the analog part of the text, uncontaminated and contaminated Poisson distribution data were respectively simulated to get good results.关键词
