Multivariate Analysis: Correlation Analysis

Overview of the Correlation Analysis

The Correlation analysis can help you to understand and visualize relationships between pairs of variables. You can use correlation coefficients to measure the strength of the linear association between two numerical variables. You can also use prediction ellipses in scatter plots as a visual test for bivariate normality and an indication of the strength of the correlation.

You can run the Correlation analysis by selecting AnalysisMultivariate AnalysisCorrelation Analysis from the main menu. The analysis is implemented by calling the CORR procedure in Base SAS software. See the CORR procedure documentation in the Base SAS Procedures Guide for additional details.
