Answer: More estimated parameters than the POT approach and shares one parameter with the POT.
## Explanation The correct answer is C because: - **Generalized Extreme Value (GEV) distribution** typically requires **3 parameters**: location parameter (μ), scale parameter (σ), and shape parameter (ξ) - **Peaks Over Threshold (POT) approach** using the **Generalized Pareto Distribution (GPD)** typically requires **2 parameters**: scale parameter (σ) and shape parameter (ξ) - **Parameter sharing**: Both GEV and POT/GPD share the **shape parameter (ξ)**, which determines the tail behavior of the distribution Therefore, GEV requires **more estimated parameters** than POT (3 vs 2) and **shares one parameter** (the shape parameter ξ) with the POT approach. This makes GEV more parameter-intensive but allows it to model block maxima directly, while POT focuses on exceedances over a threshold and can be more efficient for extreme value analysis.
