WebOct 3, 2024 · Nonlinear correlation: If the ratio of change is not constant, we are facing nonlinear correlation. [3] To measure nonlinear correlation, we use the Spearman’s correlation coefficient. More on this here [4] So back to linear correlation and Pearson’s coefficient. The coefficient always has a value between −1 and 1. WebRecall that the correlation coefficient is supposed to describe how well the two variables can be described by a linear relationship. Given that one variable (x in this case) is constant, I don't see how a line would ever describe the relationship between the two variables. ( 3 votes) Upvote michito iwata 4 years ago
