The CORRELATION Procedure

WITH Statement

WITH variables;

The WITH statement lists variables for which to compute correlation coefficients. The WITH statement requests correlations of the form , where are the row analysis variables that are specified in the WITH statement and are the column analysis variables that are specified in the VAR statement; or, if there is no VAR statement, all numeric variables that are not specified in any other statement. The correlation matrix has a rectangular structure of the form

Start 3 By 3 Matrix 1st Row 1st Column r left-parenthesis upper Y 1 comma upper X 1 right-parenthesis 2nd Column midline-horizontal-ellipsis 3rd Column r left-parenthesis upper Y 1 comma upper X Subscript m Baseline right-parenthesis 2nd Row 1st Column vertical-ellipsis 2nd Column down-right-diagonal-ellipsis 3rd Column vertical-ellipsis 3rd Row 1st Column r left-parenthesis upper Y Subscript n Baseline comma upper X 1 right-parenthesis 2nd Column midline-horizontal-ellipsis 3rd Column r left-parenthesis upper Y Subscript n Baseline comma upper X Subscript m Baseline right-parenthesis EndMatrix

For example, the statements

proc correlation data=mycas.data;
   var x1 x2;
   with y1 y2 y3;
run;

produce correlations for the following combinations:
