1. For Mon 23 Feb, ¡­

1. For Mon 23 Feb, work through (moderately extended versions of) Exercises 2.4 and 3.1.

For 2.4, re-do the analysis of Example 2.4, also supplementing the AIC with TIC numbers, involving explicit computation of Jn and Kn matrices, for each of the 2^3 = 8 models. Use glm(y ~ X, family = binomial) for the logistic regressions. Finally re-do all of this with focus on the bigger babies rather than the smaller babies, using y = 1 if birthweight is 3600 g or more.

For 3.1, include the "Beta envelope model" that has density f(x) = be(exp(-x), a, b) exp(-x). For each model, compute estimates of p = Pr(X > 0.333), with standard deviation. Here be(x, a, b) is the Beta(a, b) density at x.

2. For Mon 23 Feb I plan to use one hour to round off Ch 2, after which we start on Ch 3.
