Literature:
The course is based on handouts from the teachers. As a preparation for the course one may e.g. consult the book on Causal Inference which is being developed by Miguel Hernán and James M. Robins at Harvard University. The finished parts of this is freely available on the Internet. The course is independent of this book, but the material in the book gives a useful background.
Veier?d MB, Lydersen S, Laake P (eds.): Medical statistics in clinical and epidemiological research. Gyldendal akademisk, 2012 (www.medicalstatistics.no). This book is used as a course book in several of the PhD courses and chapter 15 is especially useful for this course.
