Exercises for Mon Oct 8

1. On Mon October 1 I went through the basics of the Cox regression model, and used time to illustrate concepts, results, interpretation, with the dataset on 238 Australian drug users. Then we ran away to listen to Ingrid Van Keilegom's talk ... on survival analysis.

2. Next week we will discuss the second most important model and method of Ch 4, namely Aalen's linear hazard rate regression model.

3. I have a couple of R scripts to upload, regarding pornscope data and the Australian drug users, and shall do this pretty soon.

4. Our two famous PhD students, Jonas S. and Riccardo P., will give 25 minute lectures, on Mon Oct 22 and Mon Oct 29; they will decide who lectures when. Their lectures will be defined as curriculum for all (and pdfs will be put on the course website).

5. Importantly, there's now a new version of the Nils Exercises and Lecture Notes (version 0.59, as of 2-x-2018, now 42 pages); you should print out a copy for yourself.

6. Exercises for Mon Oct 8: Nils Exercises 29, 32. Read carefully through Exercises 30 (which corresponds to what I did on the blackboard) and 31 (which will be used further in ABG Ch 5). The exercises involve doing more on the Australian drug users. Program the log-PL function. Compute \hat A_0(t) and survival curves for given types of users. Check for interaction effects between methadone dosage and clinic. Fit the two parametric models pointed to in Exercise 31.
