摘  要:高校数学类课程的考试成绩是每个高校学生数学素质的综合体现,但现实中存在诸多影响数学类课程成绩的因素。从我校某专业学生的数学类课程成绩出发,采用分位回归模型建立了概率统计与高考数学、高等数学及线性代数之间的关系。通过实证分析揭示了造成概率统计成绩水平不一的影响因素,并与普通最小二乘回归结果进行对比,从而得到更全面的信息,为提升我校数学素质提供实证依据。The examination scores of mathematics courses in Colleges and universities are the comprehensive reflection of each college student s mathematics quality.But actually there are many factors that affect students performance in mathematics courses.In this paper,the connection between probability and statistics,and mathematics in college entrance examination,higher mathematics and linear algebra is researched and clarified by using the quantile regression model based on the scores of mathematics courses of students from some particular major.Through the empirical analysis,this paper reveals the factors that cause different levels of probability and statistics,and compares them with the results of ordinary least squares regression,so as to get more comprehensive information and provide the empirical evidence for improving students mathematical quality.
