[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 feel confident with B. Least squares is more for regression.

Least squares doesn't seem right for extreme value analysis. I think 2 is out.

Yeah, I agree. But isn't Maximum Likelihood also a valid approach?
