Abstract:

In this paper, we study the admissibility of linear estimators of regression coefficient in linear model under balanced loss function. The necessary and sufficient condition that a linear estimator is admissible among linear estimator class is given. It shows that linear admissible estimators are also balance of estimators.

Key words: linear model, Regressional coefficient, Balanced loss function, linear admissible estimators.
