exercises for Tue Feb 14

1. On Tue Feb 7 I went through (i) the delta method, for inference about a focus parameter mu = mu(theta); (ii) the basic AIC and AIC^*. I also discussed other material from Ch 2, and discussed two ways of mixing up the Weibull -- on the f scale and the cumulative hazard scale, with application to the Old Egypt dataset.

2. I'm uploading R scripts com3c (old Egypt, mixing Weibulls); com5a (polynomial regression, Exercise 2); com6a (old Egypt, gamma-weibull-extended model). Run them, check that you understand their components, so that you may modify these scripts for later purposes.

3. Next week: I round off Ch 2, with regression models. Exercises: Do #2 (and in that connection also relevant bits of #1). And do Exam Project 2015, Exercise 2, a-b-c, involving the nerve data with n = 799 datapoints; this dataset is found on the 2015 version of the course website.
