| Abstract: | Three correlation analysis methods,including Pearson's correlation coefficient,poly-serial correlation coefficient and Spearman's rank correlation coefficient,were introduced in this paper,and the methods of parameter estimation and statistical test of each correlation analysis were also discussed.The applications of the poly-serial correlation coefficient and Spearman's rank correlation coefficient were demonstrated with two practical examples. |
