| Abstract: | By using the vectorization method of matrixes,the linearly admissible estimator of the regression coefficient of a multi-linear model with respect to linear constraints is studied under the balanced loss function.And the necessary and sufficient conditions about admissibility for linear estimators among the inhomogeneous linear class or the homogeneously linear class are obtained,respectively,which extends the results of some literature. |
