Subject: Re: Syntax for PFA
Content-type: text/plain; charset=ISO-8859-1; format=flowed
PFA is not an specification argument in SPSS.
a specification like
/DIAGONAL = .56 .5 3*.7 .61 3*.2
would allow you to specify the max correlation that a variable has.
if you specify /EXTRACTION = PAF (aka PA2)
/DIAGONAL = DEFAULT would use the conventional squared multiple
correlation as the communality estimate.
With no specification of /EXTRACTION the default is principal component
which uses ones in the diagonal and tries to account for the total variance
With specifications other than PAF, I don't know whether communality
estimates are applicable.
