Pearson spearman correlation coefficient

WebThe Pearson correlation coefficient is a parametric statistic. As such, there are distributional assumptions associated with it. Specifically, a linear relationship between X … WebTherefore, Spearman's correlation coefficient r s is simply the Pearson correlation coefficient computed using the rank values instead of the raw values of the two variables, which is why it can uncover non-linear, as well as linear relationships between X and Y, as long as Y is a monotone function of X.
