I can't find anywhere what statistical analysis IQ tests (like Weschler scales, BAS, etc.) use.
It is not stated in any of their material (that I can find at least).
I've heard it mentioned that PCA and/or hierarchical factor analysis are used?
I know historically some type of factor analysis was used (and created for) IQ testing but can't find anything for current IQ tests.
Thank you!
