What is Robust Circular-circular Correlation Coefficient about?
Many classical methods have been proposed to compute circular-circular correlation coefficients. However, these classical methods might be very sensitive to outliers in the data set. To date, no work has suggested a robust method to estimate a circular-circular correlation coefficient. The present paper aims to propose two robust methods to compute a circular-circular correlation coefficient when the circular data has outliers. The first method is computed based on the circular median, r Med , and the second on the circular trimmed mean, r Trim . A simulation study is conducted for two circular distributions: the wrapped normal and wrapped Cauchy distributions. The simulation and practical example show that the results of r Med are close to the results of classical methods. In contrast, the r Trim gives the best results and is the least affected by outliers, even with a high percentage of outliers.
