Thereby, these facts indicate that the SDE not only have better statistic properties but also have uniformly smaller mean square errors than ANOVAE in an available group of linear mixed models. The other significative following work is to generalize the idea of SDE to multivariate linear mixed model and obtain the SDE of variance component matrices which uniformly dominate the ANOVAE either.

对于含有一个随机效应的混合模型，目前文献中都仅讨论了方差分量的谱分解估计和ANOVA估计等价的充要条件，本文首次给出了方差分量的谱分解估计在均方误差意义下严格的优于ANOVA估计的理论结果，并推广到广义谱分解估计，从而说明谱分解估计不仅较ANOVA估计有更好的统计性质，而且在一类常用的模型下有更小的风险损失。

Yahoo this thing, it is to a few intermediary serve to counted computational moment to make a mistake in the ticket of shareholder plenary meeting, what write down to having a few blackball of the board of directors actually is a bit little, although the result does not have an influence, but the number of new later statistic, it is to say Yang Zhiyuan includes a few main director, 3 a few trustee that are especially inside firewood fulfil committee, include to assist Yang Zhiyuan to share the director of this negotiation, their poll bill rate is very lowly, blackball rate reachs a few partner that object them namely 30% to 40% the left and right sides, yahoo exposure is at that time 10% to 20%, have deviation so, because of recount of this shareholder requirement.

雅虎这件事情，是有一些中介服务在股东大会的票数计算时候搞错了，其实对现有董事会的一些反对票记的有点少，虽然结果没有影响，但是后来重新统计的数字，是说杨致远包括几个主要的董事，特别是在薪酬委员会里面的一些三个董事，包括协助杨致远参与这个谈判的董事，他们的投票得票率非常低，就是反对他们的一些股东反对票率达到30%到40%左右，当时雅虎披露是10%到20%，所以是有偏差的，因此股东要求重新计算。

The article discussed statistic to estimate computative meaning, value, the principle that estimation should follow, the requirement that should have reachs the specific means with computative estimation.

Adopt the generalized maximum likelihood radio test based on the Neyman-Pearson algorithm, to study two unresolved Rayleigh targets. And deduced the detection statistic which is chi-square random variable, which only need to know the conditional probability density functions of echo's measured amplitude, in-phase and quadrature of monopulse radio, but the signal-to-noise radio and the direction-off-arrival of any signal are unnecessary.

采用基于涅曼-皮尔逊准则的广义似然比检测，对不可分辨的两个瑞利目标进行了研究，推出了服从χ2分布的检验统计量，此方法只需要知道目标回波信号测量幅值的条件概率密度函数、单脉冲和差比值的同相和正交部分，而不需要任一目标信号的信噪比和DOA的先验知识。

However, the actual conditions in the market incompletely support this hypothesis. So, we turn to research the statistic distribution traits of the yield under different market conditions. To develop the investigation on securities' investment combination according to the distribution characters of conditional yield will make its actual application closer to the market facts.

然而，实际的市场情况并不完全支持这种假设，因此，我们转而研究不同市场条件下的收益率统计分布特征，根据条件收益率的分布特征进行投资组合理论研究，将使其实际应用更加贴近市场实际。
