The textbook for the course is KM:
The course will be evaluated (pass/fail) by active participation in solving exercises and miniproject and presenting solutions of exercises.

1. September 3 Slides
(updated 02.09.26). We will consider examples of duration data and discuss particular aspects of such data. Read KM Chapter 1. Solve exercises 4, 5 and 7 in catalogue of exercises.
2. September 10 Slides (updated 09.09.26). Estimation of the survival function and the cumulative hazard. Read KM 4.1-4.3. Solve exercises 6, 8, 10, 11 in exercise catalogue. Code for simulation study (updated 12.09.24). Lidt om regning med infinitesimale størrelser (updated 12.09.24).
3. September 17 (selfstudy) basic concepts: survival function, hazard function, mean residual life time. Read KM 2.1-2.4. Solve exercises 1, 2, 3, 9 and 12 in catalogue of exercises. Further, solve exercises 4.1 (a)-(d) and exercise 4.5 (a)-(c) in KM (you're welcome to use R survfit() - check documentation via help(survfit.formula)). Data from KM are available in the R-package KMsurv.
4. September 24 Lecture Cox's proportional hazards model (excluding slides on case of data with ties) (updated 22.09.26). Video lecture "asymp ties" (on youtube channel): Cox PH in case of data with ties and Cox's model for discrete time data. Read KM 8.1-8.4. Solve exercise 14, 15, 17, 18.
5. September 28 Groups present exercises. Also selfstudy this week regarding censoring and likelihoods. Read KM 3.1-3.5. Solve exercises 3.1, 3.3, 3.7 (a) and 3.8 in KM.
6. October 8 Lecture on model assessment (updated 12.10.22). Code for an example of model assessment. Code for Andersen plot and plots of cumulative hazards for stratified model. Show results regarding distributions of S(X) and H(X) on Cox-Snell slide. Solve 19 and 23 in exercise catalogue. Also give a detailed account of the profile likelihood approach for Cox's partial likelihood. Read KM 8.5, 8.8, 9.3 and 11.1-11.6.
7. October 15 We consider a simulation study of model assessment. Code for simulation study of model assessment. We next consider first 15 slides in counting processes (updated 04.11.24). Read KM section 3.6. You may also take a look at this paper. Solve exercises 1 and 2.1 in counting process slides and exercise 3.9 in KM.
8. Oktober 16 We finish counting processes. Review of counting processes and martingales. Solve exercise 2.2 and 3 in counting process slides.
9. October 29 Groups present exercises.
10. November 5 Counting processes and time-varying covariates. Slides on time-dependent covariates (updated 16.11.20). Code for analysis of bone marrow transplant data. Some advice on timedependent covariates in R. Read KM sections 9.1-9.2. Solve KM exercises 9.1 and 9.3 (note: you can use the tt() functionality for this) and exercise 27 in exercise catalogue. We also start considering frailty (updated 16.11.20) models. Start solving exercises from frailty slides.
Miniproject: Work on miniproject during week 46.
11. November 20 Selfstudy: parametric models and parametric inference. Read KM 2.5-2.6 and KM 12.1-12.5. KM exercises 2.1, 2.3, 2.9, 2.13, 2.15 (try in exercise 2.9 b) to replace 2 in front of W with 2/1.8 where 1.8 is the standard deviation of W), KM12.1, KM12.9, KM12.13.
12. November 23 We continue with frailty models. Some code for frailty models. We next consider competing risks (updated 22.11.24). Note on competing risks. Solve remaining exercises from frailty slides. Read KM 13.1, 13.3, 13.4 and 2.7.
13. November 27 We start with a brief review of parametric models and also discuss aspects of the miniproject. Next, groups present exercises.
