I took a final yesterday. It went okay. I was doing fine going in and it's a class that people from other departments take, though it's also very handy. The test results usually have a few high scores and then a long tail, and we've surmised that the high scores are, of course, the statistics students. I did a mediocre job on the take-home exam - literally doing it at the last minute - and still tied for the third highest score. I was busy. Anyway, the exams have tended to be a lot like the practice exams. A lot. Even then, though, I feel silly about something. There was a question about deriving the maximum likelihood estimates for factor scores by regression on the practice test, and I was like, yeah, whatever, you have multivariate normal things, it's just regression - condition on this, here's your covariance matrix, yada yada. Then, whaddaya know, the problem came up on the test. So a couple details got fast and loose because I was spending most of my time on the other stuff. But it was like, is it L or L^T there? etc. C'mon, it was on the practice test, I looked at it intentionally knowing it would be on there, and I still whiffed it a little.
I was digging through other old guitar stuff and ran into my Tuck and Patti CD. He has a unique style and she has a pretty good voice : https://www.youtube.com/watch?v=M56QwDjE6PQ This isn't their best, it just showcases his odd style.
Other stuff in life: apparently I have support for the idea of moving to regular "choir binders" for the choir instead of the odd arrangement we have now. Perhaps we'll be on multiple-options-for-fixed-portions-of-services sooner than I thought. Or not. At least we'll be able to support the idea.
