WebGamma correlation: The Goodman-Kruskal gamma statistic is similar to Kendall’s Tau coefficient. It is relatively robust to outliers and deals well with data that have many ties. Gaussian rank correlation: The Gaussian rank correlation estimator is a simple and well-performing alternative for robust rank correlations (Boudt et al., 2012). The Pearson correlation coefficient (r) is the most widely used correlation coefficient and is known by many names: 1. Pearson’s r 2. Bivariate correlation 3.
