PROC FACTOR Options

Use this option to specify additional PROC FACTOR options.

Leave this field blank if no additional options are needed.

You can specify PROC FACTOR options using the following syntax:

Option

where:

•	Option is the PROC FACTOR option

Some PROC FACTOR options are described in the following table:

Option	Definition
MAXITER=n	Specifies the maximum number (n) of iterations for factor extraction. The default is set to 30.
METHOD=name	Specifies the method for extracting factors.
NFACTORS=n	Specifies the number of factors (n) to retain. The default is the number of variables. Specifying a number that is small relative to the number of variables can substantially decrease the amount of memory required to run PROC FACTOR, especially with oblique rotations.
NOBS=n	Specifies the number (n) of observations. If the input data set is a raw data set, nobs is defined by default to be the number of observations in the raw data set.
NORM=name	Specifies the method for row normalization in rotation.

To Specify One or More PROC FACTOR Options:

Type the option(s) into the text field.

For example, to rescale the rows of the pattern matrix to represent covariances instead of correlations, type NORM=COV in the text box.

Be sure to separate individual options with a space.
