Bootstrap方法在测定学生智商中的应用

The Application of Bootstrap to Determination of Students′ Scientific Intelligence Quotient

将bootstrap方法引入到测定学生智商的简单模型中,建立了关于模型解释能力参数的置信区间;计算了关于主成分向量的基于稳健估计的bootstrap标准方差,并对结果进行了分析.这些对测定学生智商模型bootstrap是非常必要的.

In this paper,bootstrap method is introduced into the simple model for determining the scientific intelligence quotient,the confident interval of parameter about the degree of explanatory power for the model is constructed,the bootstrap standard error of principal component vectors based on the robust estimation is computed,and the results are analyzed.All of these are very necessary for determining students′ scientific intelligence quotient.
