| 摘 要： | 研究了Logistic回归模型,进行分组数据,计算对数发生比,为了修正异方差性,在做常规最小二乘估计之前,转换数据,建立某校学生结业考试成绩与第一学期考试成绩及学生性别关系的Logistic回归模型,结果表明, 结业考试成绩不但与第一学期考试成绩有关而且与学生性别的关系也不容忽视,为研究三者之间的关系,选择适当的方法提高学生成绩提供理论根据.

| Abstract: | This paper discusses with Logistic regression model.Logistic regression model of a certain school students' score in the first term according to total term courses and sexual is established by grouping data and counting observed logarithm ratio and transforming data before using ordinary least squares for correcting iso-square difference.It make clear that relations not only related students' scores of total courses in the first term but also individuals and sexual.According the relation study of three factors,it is benefit for improving students' study score to choose suitable method. |
