曲线回归是林业中专《数理统计》课程教学中的难点之一。由于目前通用教材中对这一部分阐述不够深入,其它数理统计书籍对此讨论也不多,因而教师中有一些模糊认识,给曲线回归部分的教学带来一定的影响;而曲线回归又是学生今后从事林业实践中用得较多的一种统计方法,因此,通过对曲线回归的进一步探讨,澄清一些看法,指出曲线回归中的若干问题是很有必要的。 Curve regression is one of the difficulties in teaching mathematics and statistics in forestry secondary school. Due to the incomplete understanding of this part of the current general teaching materials, there are not many discussions on other mathematical statistics books. Therefore, some teachers have some vague understandings, which will bring some influence to the teaching of the regression part of the curve; and the curve regression will be the future of students. There is a statistical method used in forestry practice. Therefore, through the further exploration of curve regression, some opinions are clarified and it is necessary to point out some problems in the regression of curves.
