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

CRITERIA Subcommand<br />

FACTOR 555<br />

CRITERIA controls extraction and rotation criteria.<br />

• CRITERIA can be specified anywhere after VARIABLES and MISSING.<br />

• Only explicitly specified criteria are changed. Unspecified criteria keep their defaults.<br />

• Multiple CRITERIA subcommands are allowed. Changes made by a previous CRITERIA<br />

subcommand are overwritten by a later CRITERIA subcommand.<br />

• Any CRITERIA subcommands specified after the last EXTRACTION subcommand have no<br />

effect on extraction.<br />

• Any CRITERIA subcommands specified after the last ROTATION subcommand have no<br />

effect on rotation.<br />

The following keywords on CRITERIA apply to extractions:<br />

FACTORS(n) Number of factors extracted. The default is the number of eigenvalues greater<br />

than MINEIGEN. When specified, FACTORS overrides MINEIGEN.<br />

MINEIGEN(n) Minimum eigenvalue used to control the number of factors extracted. If<br />

METHOD=CORRELATION, the default is 1. If METHOD=COVARIANCE, the<br />

default is computed as (Total Variance/Number of Variables)*n, where<br />

Total Variance is the total weighted variance principal components or principal<br />

axis factoring extraction and the total image variance for image<br />

factoring extraction.<br />

ECONVERGE(n) Convergence criterion for extraction. The default is 0.001.<br />

The following keywords on CRITERIA apply to rotations:<br />

RCONVERGE(n) Convergence criterion for rotation. The default is 0.0001.<br />

KAISER Kaiser normalization in the rotation phase. This is the default. The alternative<br />

is NOKAISER.<br />

NOKAISER No Kaiser normalization.<br />

The following keywords on CRITERIA apply to both extractions and rotations:<br />

ITERATE(n) Maximum number of iterations for solutions in the extraction or rotation<br />

phases. The default is 25.<br />

DEFAULT Reestablish default values for all criteria.<br />

Example<br />

FACTOR VARIABLES=V1 TO V12<br />

/CRITERIA=FACTORS(6)<br />

/EXTRACTION=PC<br />

/ROTATION=NOROTATE<br />

/PLOT=ROTATION.
