I Love Principal Components Analysis, and I Strongly Recommend It

I love principal components analysis, and i think it is inappropriately maligned in our field. Don't ever let somebody tell you you should not use a igen vauusand igen vectors ar magic. If you want to study the psychometric properties of how items are related to factors, I strongly recommend that you use the common factor model. And indeed, and we talked about on the factor analysis episode from season one, if you're really motivated by strong theory, you should probably move to a confirmatory factor analysis absoluy. That was like, dude, baba. Blacksheep. Who knew? Yes.
