Web22 sep. 2024 · Kendall Rank Correlation. Kendell rank correlation, sometimes called Kendall tau coefficient, is a nonparametric measure for calculating the rank correlation of ordinals variables. It can also capture both linear or non-linear relationships between two variables. There are three different flavours of Kendall tau namely tau-a, tau-b, tau-c. Web2 apr. 2024 · The correlation coefficient, r, tells us about the strength and direction of the linear relationship between x and y. However, the reliability of the linear model also depends on how many observed data points are in the sample. We need to look at both the value of the correlation coefficient r and the sample size n, together.
