Abstract: Based on the orthogonal complement likelihood function,the estimation formula for variance components was derived,and the Helmert's estimation formula was proved to be a special form under some assumed conditions.Finally,as an application example,the results solved by the above two formulas to a triangulateration geodetic network were shown.
