BAYES' ESTIMATION OF THE COMPONENTSOF VARIANCE
Zhu Jianjun(Central South University of Technology)
Bayes' estimation is a newly emerged method of estimation in the field of recent estimation theory. It's particularity lies in the fact that in addition to the information obtained in the present observation. it also makes full use of the information on the parameters obtained prior to the observation. This paper describes the principle, of esti- mating the components of variance by Bayes' estimation and the method of determini- ng the a priori distribution of variance. The expression for estimating the components of variance by Bayes' method when the a priori distribution of variance is one is der- ived. Finally, the feasibility of Bayes' estimation is illustrated by a practical example.
