Quadratic Estimates of Variance Components and Admissibility

GAO Ming,BAI Yue-qian (College of Mathematics and Computer Science,Anhui Normal University,Wuhu 241000,China)  
For the linearly mixed models,variance components are important parameters.In the paper,we mainly describe quadratic estimation of variance components with two variance components(QE).Some properties of the class quadratic estimation,such as unbiased,invariant estimation,admissibility and improving of nonnegative,are also considered furthermore.
