Pearson Correlation Coefficient

This function calculates the correlation coefficient. The correlation coefficient is a measure of the degree of the linear relationship between two characteristics that does not depend on the units of measurement and is therefore dimensionless. It can assume values between -1 and +1. With a value of +1 or -1, there is a completely positive or negative linear relationship between the characteristics considered. When the correlation coefficient is 0, the two features are not linearly related at all. However, these can nonetheless depend on one another in a non-linear manner.

To calculate, enter a series of x /y pairs (vectors). The individual numbers are separated by semicolons or spaces. Then click on the 'Calculate' button.
