PRMIA Exam 8010 Topic 5 Question 62 Discussion

Actual exam question for PRMIA's 8010 exam
Question #: 62
Topic #: 5
[All 8010 Questions]

Which of the following are valid approaches for extreme value analysis given a dataset:

1. The Block Maxima approach

2. Least squares approach

3. Maximum likelihood approach

4. Peak-over-thresholds approach

Show Suggested Answer Hide Answer
Suggested Answer: C

For EVT, we use the block maxima or the peaks-over-threshold methods. These provide us the data points that can be fitted to a GEV distribution.

Least squares and maximum likelihood are methods that are used for curve fitting, and they have a variety of applications across risk management.

I'm going to go with option B. The Block Maxima and Peak-over-thresholds approaches are the classic techniques, and the maximum likelihood approach is a solid backup plan. As for the least squares approach, that's like trying to use a screwdriver to hammer a nail - it just doesn't fit the job.

I'm not so sure about the least squares approach though, it might not be the best fit.

Option C, all the way! The Block Maxima and Peak-over-thresholds approaches are the bread and butter of extreme value analysis. The other two options are just unnecessary fluff, in my opinion.

Hmm, I'm torn between options B and D. The maximum likelihood approach is a bit of a wild card, but it could be a sneaky hidden gem in this question. I might just go for the gold and select D - all of the above.

I'm going with option B. The Block Maxima and Peak-over-thresholds approaches are specifically designed for extreme value analysis, and the maximum likelihood approach is a powerful tool that can also be used in this context.

The Block Maxima approach and the Peak-over-thresholds approach seem like the most logical choices for extreme value analysis. The least squares approach is more for linear regression, and the maximum likelihood approach is a bit overkill for this task.

Yeah, I think that makes sense. The least squares and maximum likelihood approaches might not be as relevant in this case.
