VARIABLES Subcommand (CORRELATIONS command)
VARIABLES
specifies the variable list.
- A simple variable list produces a square matrix of correlations of each variable with every other variable.
- Variable lists joined by the keyword
WITH
produce a rectangular correlation matrix. Variables beforeWITH
define the rows of the matrix and variables afterWITH
define the columns. - The keyword
ALL
can be used on the variable list to refer to all user-defined variables. - You can specify multiple
VARIABLES
subcommands on a singleCORRELATIONS
command. The slash between the subcommands is required; the keywordVARIABLES
is not. - If only varlist1is specified, the
confidence limits are estimated for each different pair of the variables contained within
varlist1. If
varlist1 WITH varlist2
is specified, the confidence limits are estimated for each different pair of the variables with one contained within varlist1 and the other varlist2. The confidence limits of the pair containing a variable and itself are not estimated.
Example
CORRELATIONS VARIABLES=FOOD RENT PUBTRANS TEACHER COOK ENGINEER
/VARIABLES=FOOD RENT WITH COOK TEACHER MANAGER ENGINEER
/MISSING=INCLUDE.
- The first
VARIABLES
subcommand requests a square matrix of correlation coefficients among the variables FOOD, RENT, PUBTRANS, TEACHER, COOK, and ENGINEER. - The second
VARIABLES
subcommand requests a rectangular correlation matrix in which FOOD and RENT are the row variables and COOK, TEACHER, MANAGER, and ENGINEER are the column variables.
