基于Kullback-Leiber距离粗差探测的Bayes方法
BAYESIAN APPROACH TO DETECTION OF GROSS ERRORS BASED ON DIVERGENCE OF KULLBACK-LEIBER
摘要
Abstract
With the view of influence analysis, a new Bayesian method for gross errors detection based on divergence of Kullback-Leiber is proposed. Under the condition of unequal weight and independent observations, a comparison among the data deletion model, the variance inflation model and the mean shift model based on certain prior distribution is made, and the computational formula of divergence of Kullback-Leiber about the three models is given and a judge rule of gross error detection is established. Finally, the method is used for gross error detection in triangulateration network and a good result is obtained.关键词
