The course is intended for doctoral students at the medical faculty with research projects suited for survival analysis. The course is, conditional on availability, also intended for post-doctoral students and others with a special interest in survival analysis at the medical faculty and for doctoral students, post-doctoral students and others with special interest outside of the medical faculty. Although the latter may consitute at most 50% of course participants. All course attendants must have prior knowledge in applied statistics corresponding to course levels I and II. Access to and substantial skills in a statistical software packages are also required: SPSS, SAS, STATA, R or equivalent.
