5.1 Correlate - correlation measures
The command correlate is a tool for analyzing statistical correlations between variables. Values ranging from -1 to 1 are reported in a correlation matrix for the specified variables, where minus- and plus-values implicate negative and positive correlation respectively. The value 0 indicates no correlation. The closer to +/- 1, the stronger is the estimated correlation.
Syntax:
correlate <variable list> [if <condition>] [, <options>]
If no variable is specified, a correlation matrix for all variables in the dataset is presented.
The following options may be used to present alternative measures:
-
covarianceShow covariance instead of correlation coefficient -
pairwisePairwise presentation -
obsShow number of observations behind each correlation coefficient -
sigShow significance value for each correlation coefficient
