Hi, if you check the 'Mean difference" option does that give you what you need?

Hi, thanks for the heads-up. I've updated the book with the revised CI from version 1.05. This should be avaliable for download right away on learnstatswithjamovi.com.

Best.

That's great, thanks jonathon

also, in case anyone else is interested, I found the answer posted here helpful (even if I didn't understand all of it!):

aah, pattern vs structure matrix!! Sorry I'm a bit rusty on fa

Further digging shows that with orthogonal rotation (varimax) factor loadings combine correctly to displayed uniqueness, but not for oblique rotation (promax). Extraction method doesn't seem to make a difference.

Using factanal handcalc uniqueness = 0.66 but displayed = 0.74, just like in psych. Probably something happening that I don't understand...I had thought that rotated factor loading should still sum to same communality / uniqueness as unrotated?

..answering my own question, NFactors = 2 or NFactors = 5 in jmv syntax doesn't change things...

jmv syntax shows nFactors = 2 but five are extracted using parallel method...could this be something to do with it? See attached.
