new version of handouts/book on SEM

[Phil Wood]

Hi folks, 

I added material to the book on Amazon. This version now includes more material on exploratory factor analysis and dependent categorical variables (including Rasch modeling, two paramter IRT, and growth curve models with categorical dependent variables). 

You can either but it here or, if you are in the US, let me know and I'll send you an author copy for $10 (which includes shipping). Hope you are all doing well during the current plague. Phil
