摘要
The unbiased estimator of risk of the orthogonally invariant estimator of the skew-symmetric normal mean matrix is obtained. and a class of minimax estimators and their order-preserving modification are proposed. The estimators have applications in paired comparisons model. A Monte Carlo study to compare the risks of the estimators is given.
