| Abstract: | We bring the fact to light that the admissibility of the linear estimate in growth curve model under matrix loss is identical with that of the linear estimate in the restricted single linear model under matrix loss. From that we can easily obtain the necessary and sufficient conditions for DYF to be admissible estimators of the linear function KBL in the homogeneous linear class. |
