FACTOR 553<br />

DET Determinant of the correlation or covariance matrix, depending on the specification<br />

on METHOD.<br />

INV Inverse of the correlation or covariance matrix, depending on the specification<br />

on METHOD.<br />

AIC Anti-image covariance and correlation matrices (Kaiser, 1970). The measure<br />

of sampling adequacy for the individual variable is displayed on the diagonal<br />

of the anti-image correlation matrix.<br />

KMO Kaiser-Meyer-Olkin measure of sampling adequacy and Bartlett’s test of<br />

sphericity. Always based on the correlation matrix. Not computed for an<br />

input matrix when it does not contain N values.<br />

REPR Reproduced correlations and residuals or reproduced covariance and residuals,<br />

depending on the specification on METHOD.<br />

FSCORE Factor score coefficient matrix. Factor score coefficients are calculated<br />

using the method requested on the SAVE subcommand. The default is the<br />

regression method.<br />

ALL All available statistics.<br />

DEFAULT INITIAL, EXTRACTION, and ROTATION.<br />

Example<br />

FACTOR VARS=V1 TO V12<br />

/SELECT=COMPLETE (‘yes’)<br />

/MISS=MEANSUB<br />

/PRINT=DEF AIC KMO REPR<br />

/EXTRACT=ULS<br />

/ROTATE=VARIMAX.<br />

• This example specifies a factor analysis that includes all variables between and including<br />

V1 and V12 in the working data file.<br />

• Only cases with the value “yes” on COMPLETE are used.<br />

• Variable means are substituted for missing values. Only values for the selected cases are<br />

used in computing the mean. This mean is used to substitute missing values in analyzing<br />

the selected cases and in computing factor scores for all cases.<br />

• The output includes the anti-image correlation and covariance matrices, the Kaiser-Meyer-<br />

Olkin measure of sampling adequacy, the reproduced correlation and residual matrix, as<br />

well as the default statistics.<br />

• Factors are extracted using unweighted least squares.<br />

• The factor pattern matrix is rotated using the varimax rotation.<br />

PLOT Subcommand<br />

Use PLOT to request scree plots or plots of variables in rotated factor space.<br />

• If PLOT is omitted, no plots are produced. If PLOT is used without specifications, it is<br />

ignored.
