直线相关系数 meaning in Chinese

linear correlation coefficient

In chapter 4 , mathematical theory about related coefficient and fitting of straighten anti - curve line is introduced at the beginning of this chapter , then how to program to calculate related coefficient is introduced including discussing the appearance of straighten anti - curve line in bitmap , searching the ends of straighten anti - curve line , calculating the angle bitmap should be turned , calculating related coefficient after bitmap has been turned
第4章首先介绍了有关相关系数以及直线拟合的数学理论，然后阐述了求解逆直线相关系数的编程思路，其中包括对逆直线在位图中摆放方式的分类讨论、逆直线端点的搜索、求解旋转角度、旋转后求解相关系数等几个环节。
