| Abstract: | Under the quadratic loss function, the admissibility of nonnegative quadratic estimate of error variance in a linear model with uniform covariance structure is studied, some sufficient and necessary conditions of admissibility of an estimator are gained when the designed matrix is an n×1 vector with only 1 element. |
