Matematika neživotního pojištění 2 - cvičení
Section outline
-
- Practicals take place once a week, every Friday 10:40-12:10, starting on 25.2.2022 in K3. Classes will be conducted in present form, as long as it is possible.
- Supporting materials for the practicals will be shared via this Moodle page soon after the session.
- To successfully pass the practicals, you will have to work out and present your home project at the end of the semester. The task will be mainly to model frequency and severity of claims using appropriate methods based on GLM. Specific instructions and data will be assigned to you during the semester. The solution report (incl. relevant source code and software outputs attached in the appendix) must be uploaded into this Moodle page as one pdf document.
- In case of any questions or troubles, do not hesitate to contact me via e-mail (kriz@karlin.mff.cuni.cz) or in person. -
Covers practicals on 25.2.2022
-
Covers practicals on 4.3.2022
Contains exponential dispersion family, link function, maximum-likelihood.
Note: Exercises 2 and 4 serve as preparation for parameter estimation in GLM (will be done in detail next week), but you should be able to work them out.
-
Covers practicals on 11.3.2022
Contains equations for MLE and their numerical solution.
-
GLM - specifics of the models for claims frequency and claims severity (with multiplicative structure)
-
GLM - model diagnosis and variable reduction analysis
-
GLM - approximate confidence intervals (based on Fisher information) for model coefficients, risk factors and predicted expectations
-
The case study on the frequency-severity approach to tariffication based on GLM applied to real-world Moped insurance data.
The commented case study is available on the website of doc. Pešta:

-
GLM in loss reserving - discussion of possibilities to approximate distribution of future claims based on historical claims (arranged into the development triangle) and to determine prediction intervals. See "exercises" file.
Assignment of the projects to teams - will be distributed via emails.
