552 FACTOR<br />

Example<br />

FACTOR VARIABLES=V1 TO V12<br />

/MISSING=MEANSUB<br />

/FORMAT=SORT BLANK(.3)<br />

/EXTRACTION=ULS<br />

/ROTATION=NOROTATE.<br />

• This example specifies an analysis of all variables between and including V1 and V12 in the<br />

working data file.<br />

• The default CORRELATION method is used.<br />

• The MISSING subcommand substitutes variable means for missing values.<br />

• The FORMAT subcommand orders variables in factor pattern matrices by descending<br />

value of loadings. Factor loadings with an absolute value less than 0.3 are omitted.<br />

• Factors are extracted using unweighted least squares and are not rotated.<br />

PRINT Subcommand<br />

PRINT controls the statistical display in the output.<br />

• Keywords INITIAL, EXTRACTION, and ROTATION are the defaults if PRINT is omitted or<br />

specified without keywords.<br />

• If any keywords are specified, only the output specifically requested is produced.<br />

• The requested statistics are displayed only for variables specified on the last ANALYSIS<br />

subcommand.<br />

• If more than one PRINT subcommand is specified, the last is in effect.<br />

• If any ANALYSIS subcommand is explicitly specified, all PRINT subcommands specified<br />

before the last ANALYSIS subcommand are ignored. If no PRINT subcommand is specified<br />

after the last ANALYSIS subcommand, the default takes effect.<br />

INITIAL Initial communalities for each variable, eigenvalues of the unreduced<br />

correlation matrix, and percentage of variance for each factor.<br />

EXTRACTION Factor pattern matrix, revised communalities, the eigenvalue of each factor<br />

retained, and the percentage of variance each eigenvalue represents.<br />

ROTATION Rotated factor pattern matrix, factor transformation matrix, factor correlation<br />

matrix, and the post-rotation sums of squared loadings.<br />

UNIVARIATE Valid number of cases, means, and standard deviations. (Not available with<br />

matrix input.) If MISSING=MEANSUB or PAIRWISE, the output also includes<br />

the number of missing cases.<br />

CORRELATION Correlation matrix. Ignored if the input is a factor loading matrix.<br />

COVARIANCE Covariance matrix. Ignored if the input is a factor loading matrix or a correlation<br />

matrix that does not contain standard deviations (STDDEV or SD).<br />

SIG Matrix of significance levels of correlations.
