Exercises for Mon Oct 22

1. On Mon Oct 15 I discussed material for Aalen's linear hazard rate regression model (Ch 4), and also parametric regression models (Ch 5). I went through exercises, including the famous Australian drug users, also via parametric models of the type \alpha(s,\theta)\exp(x_i^\tr \beta).

2. PhD student Jonas Schenkel wil use 25 minutes on Mon Oct 15, to tell us about lasso for Cox.

3. An extra half hour, for those who want to, Mon Oct 22 (I have piano lessons every second Monday, so on the other Mondays I can offer such extra half-hours).

4. I'm uploading my com27b script, which does a somewhat simple version of the Aalen linear hazard regression model.

5. For Mon Oct 22, first do the Australians again, with x = methadone dose as the single covariate, but for clinic I and clinic II separately. Compute and display the B_{1,clinic1} and B_{1,clinic2} curves. Compare them and test if they are equal.

Then go to *earlier exam sets*, now posted on the course site, and do these: December 2010, Exercises 2 and 3.

6. How many presidents were there, in France, in the period 1792 to 1795?
