这只是意味着这种关系不是线性的。 2.回归(Regression) 回归分析是一种数学技术,用于分析一些数据,包括一个因变量和一个(或多个)自变量,目的是找到因变量和自变量之间的最终函数关系。 回归分析的目的是找到在因变量和自变量之间的一个估计值(一个好的估计值!)。从数学上讲,回归的目的是找到最适合数据的曲线。 当然,最适合数据的曲线可以是直线

In other words, we assume that Y is a dependent variable and X an independent variable: Y depends on X. Then we discuss the bivariate normal relationship and concepts related to the correlation coefficient.doi:10.1007/978-1-4614-5897-5_13Cheng-Few Lee...
if r doesn’t show on your calculator, then diagnostics need to be turned on. This is also the same place on the calculator where you will find the linear regression equation and the coefficient of determination.

There are different types of coefficients quantifying different types of correlations in terms of how the variables relate to each other - linear / non-linear, functional / non-functional, etc. (see Pearson's vs. Spearman's vs Kendall's coefficient below). As any other statistic, a coefficie...
The Pearson correlation coefficient (r) is the most common way of measuring a linear correlation. It is a number between –1 and 1 that measures the strength and direction of the relationship between two variables. Pearson correlation coefficient (r)Correlation typeInterpretationExample Between 0 ...
