Pretty Much Wiped Out

We are moving into the last part of the semester.

I have five days of classes left, spread out over the next 11 days or so.

In Intro Probability, we're just doing review. The review is really tough -- we have some old exams given by Professor T that involve some counting problems where you have to use permutations and know that P(1)P(2) is the same as P(2)P(1)...those old "how many ways can you arrange the letters in "HEIGHT" so that the two Hs are two spaces away?" kind of problems. Either I've forgotten everything I've learned since January (which might be possible, P=0.02) or I've just not been challenged enough.

Dr. S has returned from his day off -- a grad assistant gave us the test on Monday. We had eight problems. Solving five of them was considered to be a good grade. We haven't got the test back yet, so since he has five days of class, he's talking about...well, I don't know what he's talking about. Something about econometrics, the value of a claim Y at time t (Y-sub t) where Y-sub-t = Y-bar plus X_sub-(t-1) plus nu*N(t), where N(t) is standard normal. It turned into a big, normal p.d.f. mess. He said he'd write it up, and if he plans on testing us on this, he'd better. (Will I have to know this crap in grad school? Good grief!!)

I've already started studying for Dr. Z's Intro Stats class. It's going to involve a lot of memorization, knowing how to find z-sub(alpha/2), t-sub(alpha/2) with df=(n-1), one sample and two sample tests, and so on.

Other than that, no news. If something happens, I'll let you know.
