WebNov 22, 2014 · The Pearson correlation coefficient measures the linear relationship between two datasets. Strictly speaking, Pearson's correlation requires that each dataset be normally distributed. Like other correlation coefficients, this one varies between -1 and +1 with 0 implying no correlation. WebThe Kendall tau-b correlation typically is smaller in magnitude than the Pearson and Spearman correlation coefficients. The 95% confidence intervals are (0.5161, 0.9191) and (0.4429, 0.9029), respectively for the Pearson and Spearman correlation coefficients.
