Hi Ed
I think I'll enter this comment using "anonymous" but sign my name to it--is that what you were hoping for us to do?

I was wondering about course registration. I am still on the waitlist for 7396 and I wasn't sure if the class cap would automatically increase and all of us waitlisters would just become enrolled or if a form was needed.

Looking at the "Statsfear and Final Exam Score" output p.2 "Explore" the histograms of unstandardized residuals for both treatment groups, I want to make sure I am reading the x-axis correctly. Is the scale increasing by 1.33 units as you move from left to right?
What do you mean in Problem Set 1 when you ask for "the matrix algebra representation for factor analysis"?
Would you like the problem set 1 homework via email or a hard copy, or both?
I get an error when I try to download Stevens, chapter 2. My browser (firefox) cannot find the document corresponding to the URL.
In case anyone else was perplexed... there are two other typos in the T&F appendix you posted, as well (although one is corrected in the 5th edition of the book).
1. On page 914 of the posted version, equation A.13, in X13 it should be "bf-ce" not "bf-cd." This is corrected in the 5th edition of the book.
2. On page 914 of the posted version, and page 930 in the 5th edition, the value of X12 in the inverse of A should be POSITIVE 1.33 not "-1.33." Just a tiny error but it makes a big difference when "testing" the inverse.
i'm a little confused concerning whether or not factors are "causal" or if they can be both causal (as in independent variables), or an outcome (as in dependent variables), or both! For example, figure 14.2 in our book shows the factor "grad school success" as causal of observed variables and an outcome gender and undergrad success.
We are having a hard time figuring out if there is any difference between a factor and a latent variable. They seem to be the same thing...
