[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.

Least squares? Not sure that fits in extreme value analysis.

Hmm, I'm a bit confused by this question. I know the Block Maxima and Peak-over-thresholds approaches are used for extreme value analysis, but I'm not sure about the other two options. Maybe I should try to eliminate the ones I'm less sure about and see if that helps me narrow it down.

I'm pretty confident I know the answer to this one. The Block Maxima and Peak-over-thresholds approaches are definitely valid for extreme value analysis, and the Maximum likelihood approach is also a common technique. I'll mark B as my answer.

Okay, let's see. The Block Maxima and Peak-over-thresholds approaches seem like they could be relevant, but I'm not sure about the Least squares and Maximum likelihood approaches. I'll need to review my notes on extreme value analysis to be sure.

Hmm, this looks like a tricky one. I'll need to think carefully about the differences between these approaches and which ones are valid for extreme value analysis.

The Peak-over-thresholds approach sounds like the most extreme way to analyze extreme values. I'm just picturing someone standing on a cliff, yelling 'PEAK!' every time a data point exceeds the threshold.

Maximum likelihood is a standard technique for parameter estimation, so I'd expect it to be a valid approach for extreme value analysis. The question seems to be testing our knowledge of different statistical methods.
