| Abstract: | In correlation analysis, correlation efficient is usually used to analyze or measure the degree of linear dependence between variables. Correlation coefficient is the indicator of the linear correlation degree between two random variables. The calculation and analysis of the correlation coefficient is a simple method in scientific research. Clustering analysis is based on correlation coefficient. In this paper, the concept of correlation coefficient is firstly introduced, then the calculation method of correlation coefficient is given, and several applications are enumerated at last. |
