Text Response

Matrices are not intuitive for me. I don't see the rotation for multiplication of matrices.

4. Did the class move at the right speed for you today?

The matrix material was paced fine; however, the introduction to the lab was too quick to really follow. The matrix material in itself is clear. I don't yet fully understand how to translate it into regression. I know we will get more into that in the next class, but it feels like the Thursday lab material may be getting a little ahead of what we've covered in class. So I hope it won't be too fast.

As I was writing notes down from your chalktalk, I was starting to piece what I was learning together with something you'd said earlier. Bu the time I looked up, you'd erased what you'd written so I missed it. I'll go back to the slides and try to reconstruct what I missed. 
6. Do you have any specific questions regarding this lecture/lab or the class in general?

Thank you for sending out these surveys and for following up after every class  I find them very helpful. Even if I don't have any problems with a particular class I can rest easy knowing that if I did I would have a place to express that. Thanks again!

This was a great lecture. It was nice to revisit matrices, and I especially liked the end where you did a regression in stata through matrices. I think it would be helpful if you used more visual examples to demonstrate some of the concepts you were talking about as you did in earlier lectures. It's nice to see how some of these concepts can be represented graphically.

Perhaps the first time an example of something is given, e.g., the 2*3 matrices transformation, all of the steps could be written out.
