| Abstract: | The paper derives the maximum conditional probability density estimation formulae of extended networks and its estimation formulae of Helmert type,Welsch type,Forstner type for variance componets when there are two types of uncorrelated observation in these networks. A case history is given to illustrate its application effect. |
