| 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. |
