Today, I will talk to you about the reference materials about the canonical correlation analysis of R language, which may not be well understood by many people. in order to make you understand better, the editor has summarized the following contents for you. I hope you can gain something according to this article.
Canonical correlation analysis (Canonical Correlation analysis, CCA) is a statistical method to study the correlation between two groups of variables. If each set of variables contains only one variable, the correlation can be measured by the correlation coefficient. However, the number of variables in each group of variables is greater than 1, such as temperature and humidity in group An and DBH in group B. to measure the correlation between these two groups of variables, we can use the idea of principal components to transform the correlation between the two groups of variables into the maximum possible correlation of the two comprehensive variables, namely canonical correlation analysis (CCA). -- extracted from Applied Statistical Analysis and R language practice
