MATRIX Subcommand (CORRELATIONS command)

MATRIX writes matrix materials to a data file or previously declared dataset (DATASET DECLARE command). The matrix materials include the mean and standard deviation for each variable, the number of cases used to compute each coefficient, and the Pearson correlation coefficients. Several procedures can read matrix materials produced by CORRELATIONS, including PARTIAL CORR, REGRESSION, FACTOR, and CLUSTER.

• CORRELATIONS cannot write rectangular matrices (those specified with the keyword WITH) to a file.
• If you specify more than one variable list on CORRELATIONS, only the last list that does not use the keyword WITH is written to the matrix data file.
• The keyword OUT specifies the file to which the matrix is written. Specify an asterisk to replace the active dataset or a quoted file specification or dataset name, enclosed in parentheses.
• Documents from the original file will not be included in the matrix file and will not be present if the matrix file becomes the working data file.
