Exercises and solutions

 

Exercises for week 16 (21.04): There are no new ordinary exercises for this week. Instead you may prepare for the discussion of exam exercises in the lecture 21.04: The plan is to go more or less thoroughly through 2016,1 (Kaplan-Meier); 2016,3 (survival regression); 2019,4 (nonparametric tests); 2020,3 (additive regression). For more recommended exam exercises, see the list given here

Solution (sketch) of the obligatory exercise is found here

Exercises for week 12 (24.03): You should work on the obligatory exercise. If you have time, you may do Problem 3 in Exam January 2020 (this exercise will otherwise be given for the first lecture after Easter, 07.04). 

Exercises for week 11 (17.03): You should work on the obligatory exercise. You may also go through the R-tutorial on Aalen's additive regression model (see Computing).

(3) Go through the R-tutorials on ties for the Nelson-Aalen estimator, and the tutorial for left-truncation (see Computing).

Exercises for week 7 (17.02): (1) Exercise 2.12 (p. 67 in ABG) Hint: Prove first that W(t) itself is a martingale and find its predictable variation. Look at Section 2.1.1 in ABG, and Slides 5; Solution Ex 2.12 in ABG.  (2) Reconsider the asymptotics at the end of Exercises E1.1 and check how the theory is applied. (3) Do Problem 1 of Exam in STK4080/9080 December 2012. (4) You may also have a look at the R-tutorial for the Kaplan-Meier estimator (see Computing), which is the main topic for the lectures on 17.02.  .
