Topic #: 1

[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

A2 and 3

B1, 3 and 4

C1 and 4

DAll of the above

Show Suggested 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.

Hold up, the Least squares approach? What is this, a beauty pageant? The only valid answers are the ones that actually make statistical sense.

Whoa, all four of those are valid? I thought it was just the Block Maxima and Peak-over-thresholds. Looks like I need to brush up on my extreme value analysis methods.

The Maximum likelihood approach is definitely one of the valid options. I'm not sure about the Least squares approach, that sounds more like a regression thing.

I'm pretty sure the Block Maxima approach and the Peak-over-thresholds approach are valid for extreme value analysis. The Least squares approach seems a bit off-target though.

The Least squares approach doesn't seem to fit the bill for extreme value analysis.
