[Ifeffit] Sixpack, PCA controll, "IND" column

[Baker, Leslie]

This is the factor indicator function.  Its minimum can be used to
indicate the correct number of meaningful factors.  

There's an explanation here:

For more information, see Malinowski's book Factor Analysis in
Chemistry.

Hello,

does anyone know the meaning of the IND column in the PCA controll field
of sixpack (version 0.63)?

I did not found a hint in the sixpack documentation.

Best regards
Joerg
