In this article, we will explore the theory, assumptions and interpretation of Pearson’s correlation, including a worked example of how to calculate Pearson’s correlation coefficient, often referred ...

How to Calculate the Correlation Coefficient A simple calculation method is to use what's known as the Pearson correlation coefficient calculator, named after the English mathematician Karl Pearson.

The correlation coefficient is a number between 1 and -1. A number close to 1 means two factors are positively correlated—they rise or fall together and at the same magnitude.

You can calculate the correlation coefficient to find the correlation between any two variables, whether they are market indicators, stocks, or anything else that can be tracked numerically.

In this paper the robustness of some well known correlation coefficients, namely, Pearson's, Spearman's and Kendall's, are examined. The empirical evidence shows that these correlation coefficients ...
