Emilia Forslin: Estimation of the risk of the occurrence of events of interest over time with applications to medical data

Abstract.

In medical research it is common to study the time to the occurrence of a single event that may only happen once per individual. One such typical event is the occurrence of a death and the studying of the survival time. Even though the analysis of this type of one-time-only event is very common, classical theory in event history analysis fail to give a logical measurement of the risk of occurrence of these events.

In the article by Bottai [2017] the theoretical ground for two new measurements, for these type of events, were presented; the incidence rate and the event-probability function.

The aim of this thesis is to make the usability of these two measurements visible and easily accessible by giving a thorough theoretical explanation, presenting new software, and providing a real data example.
