Update on lecture schedule and a note on Problem #1

I realized over the weekend that trying to answer the first question on Problem #1 with WinBUGS involves more complicated coding than I've introduced so far. If you're interested in how to do it, I'd be happy to do so, but just stick with the chi-squared or Fisher's exact test for now.

If you've looked for changes in the lecture schedule, you'll notice that they haven't appeared. That's because I've decided to leave things as they are. We'll catch up by

• Skipping the Bayesian version of the ABO example (for now, we'll come back to it later).
• Skipping the explicit discussion of identity by descent. We'll encounter the concept several more times anyway, and I'll tell you what you need to know about it then.
• Spending a little less time on testing for departures from Hardy-Weinberg. I'll focus on the Bayesian approach, since you'll need ideas from it to answer the third question on the problem set.
• Focusing on the conceptual basis of Wright's F-statistics, and skipping some of the algebra I'd initially planned to cover. (Please wipe that smile off your face.)

With those modifications we should finish up on the 15th with everything you'll need to do Project #1, which will be assigned that day.

We'll go over how to use WinBUGS again in class tomorrow. If you'd like to follow along, bring your computer and download the files
