Principal Components and Factor Analysis

Select the Quick tab of the Define Method of Factor Extraction dialog box to access options to quickly specify a method of factor extraction. For more detailed options, see the Advanced tab and the Descriptives tab.

Maximum no. of factors. The number entered into the Maximum no. of factors box specifies how many factors will be extracted. Note that this box works in conjunction with the Minimum eigenvalue field described below it; that is, STATISTICA will extract either as many factors as requested or as many as have eigenvalues greater than that specified in the Minimum eigenvalue box, whichever criterion yields a fewer number of factors.

Minimum eigenvalue. The number entered into the Minimum eigenvalue box specifies how many factors will be extracted; that is, STATISTICA will extract as many factors as there are eigenvalues greater than the number specified in this box. Note that this box works in conjunction with the Maximum no. of factors box (see above).
