We develop Mardia's concept of a linear-circular correlation coefficient, obtaining distributions of statistics under various hypotheses. Mardia's data on simian natality are discussed in the light of ...

Pearson correlation coefficient formula The formula for Pearson’s correlation coefficient, r, relates to how closely a line of best fit, or how well a linear regression, predicts the relationship ...

We propose some correlation coefficients when one variable is linear and another is circular. These are motivated by a study which investigates the relationship between geographic latitude and simian ...

You've probably noticed certain things that have a clear relationship with one another. For example, the amount of petrol your car uses increases along with the number of kilometres you drive. Or, if ...

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.
