二分搜索法 meaning in English

dichotomous question

To solve his problem , we propose three kinds of diagnostic procedures . the first one is binary depth search technique , which divides the total variables into two partial variables and remove correlation of one partial variable to the other by residual analysis , then use residual vector to construct hotelling t2 statistic and to seek which partial variables are out of control . once out - of - control partial variables are determined , we utilize binary depth search on these variables further until variables being out of control are identified
为了解决这一问题，我们采用了以下几种方法: ( 1 )提出了二分搜索法并进行了仿真分析，即把整个变量分成两个部分，通过残差消除一部分变量对另一部分变量的影响，然后再利用残差向量建立hotelling统计量，这样可以区分哪些部分变量失控，确定部分失控变量之后，再利用二分法直到某一步，最终找到某个/某些失控变量。
