中文摘要：
主要考察了零成分搜索法的模拟分析.首先简述了零成分搜索法的计算步骤,其次用一个模拟例子阐述了零成分搜索法的应用过程;最后模拟计算了零成分搜索法进行列显著性判断时所犯两类错误概率的大小.模拟分析结果表明,零成分搜索法不仅可以较好地识别不显著列,而且对误差方差的估计也有不错的结果.
英文摘要：
The simulation analysis of Searching Zero-Decompostion was studied.Firstly,the step of Searching Zero-Decompostion was listed.Secondly an example to simulate the procedure of Searching Zero-Decompostion was specified.Thirdly the probability of two types of errors was also calculated when judging a colume is significant or not.The results simulation analysis illustrated that Searching Zero-Decompostion not only distinguishs the non-signficant column from unknown column successfully,but also estimates the variance of errors well.
