    文章对病态的聚集数据模型,提出了新的有偏估计,其中对模型中的参数要求大于零。讨论了这种新的有偏估计的优良性,证明了此估计改进了岭估计（均方误差意义下）,推广了已有的结果。

    For the linear model with aggregated date,this paper gives a class of biased estimator.A class of biased estimator is a parameter where is More than 0.We discussed An class of biased estimator.It has some superiority in the sense of mean square error;.The related results are extended.
