This paper discusses the estimation of scoring itemparameters. The solutions of parameters are gained and the convergence of solutions is proved.
主要讨论二级评分项目的参数估计,提出了一种二级评分项目的参数解法,并对该方法的收敛性进行了证明。

The dimension of Scoring matrixes X is descended by using scoring rate or passing rate or coefficient of correlation or guess rate when estimating those itemparameters.
在对这些参数进行估计时,将得分矩阵分别采用得分率、通过率、相关系数、猜测率进行降维处理。

To do this, we set the start - and end-date parameters when we create our profile item.
