NumberOfFactors Class

The
NumberOfFactors
class contains static methods for creating function objects suitable for use as "number of factors" functors used in the factor extraction step of a factor analysis. These functions take as paramters the eigenvalues and eigenvectors values computed during factor extraction and return the number of factors to "keep".

Methods
  NameDescription
Public methodStatic memberEigenvaluesGreaterThan
Creates a functor which computes the number of eigenvalues greater than the specified minimum value.
Public methodStatic memberEigenvaluesGreaterThanMean
Creates a functor which computes the number of eigenvalues greater than a given factor times the mean of the eigenvalues.
Public methodStatic memberFixedNumber
Creates a trivial functor which returns a fixed number for the number of factors to retain in a factor analysis.
Public methodStatic memberSelectAll
Creates a trivial functor for specifying "keep all the factors". Just returns the number of eigenvalues/eigenvectors.
