SELECT Subcommand (FACTOR command)
SELECT
limits
cases used in the analysis phase to those with a specified value for
any one variable.
- Only one
SELECT
subcommand is allowed. If more than one is specified, the last is in effect. - The specification is a variable name and a valid value in parentheses. A string value must be specified within quotes. Multiple variables or values are not permitted.
- The selection variable does not have to be specified
on the
VARIABLES
subcommand. - Only cases with the specified value for the selection variable are used in computing the correlation or covariance matrix. You can compute and save factor scores for the unselected cases as well as the selected cases.
-
SELECT
is not valid ifMATRIX = IN
is specified.
Example
FACTOR VARIABLES = V1 TO V10
/SELECT=COMPLETE(1)
/SAVE (4).
-
FACTOR
analyzes all ten variables named onVARIABLES
, using only cases with a value of 1 for the variable COMPLETE. - By default,
FACTOR
uses theCORRELATION
method and performs the principal components analysis of the selected cases. Those with eigenvalues greater than 1 are rotated using varimax rotation. - Four factor scores, for both selected and unselected cases, are computed using the default regression method and four new variables are saved in the active dataset.
