WebPearson Correlation Formula. The name correlation suggests the relationship between two variables as their Co-relation. The correlation coefficient is the measurement of correlation. To see how the two sets of data are connected, we make use of this formula. The linear dependency between the data set is done by the Pearson Correlation coefficient. WebKendall Rank Correlation- The Kendall Rank Correlation was named after the British statistician Maurice Kendall. It measures the dependence between the sets of two random variables. In the case of rejection of correlation calculated from Spearman's Rank Correlation, the Kendall correlation is used for further analysis. Classic correspondence analysis is a statistical method that gives a score to every value of two nominal variables. In this way the Pearson correlation coefficient between them is maximized. There exists an equivalent of this method, called grade correspondence analysis, which maximizes Spearman's ρ or Kendall's τ. crest geology definition
