In the first article [Lebrun R, Dutfoy A. An innovating viewpoint of the isoprobabilistic Nataf transformation with the copula theory within exceedance threshold uncertainty analysis. Probabilistic Structure Engineering Structural Reliability.
Here, the exceedances threshold was set to five.
There is a bias-variance trade-off in selecting the exceedances threshold.
The exceedances threshold t is set to (y N exc*+ y N exc+1* /2 (assuming that the values of Y are ordered from high to low as before).
Setting the exceedance probability threshold at 0.8, and the standardised measures threshold at 3 (Wilcox, 2016, page 45), reduces performance for the first four measures (Table 3, lower panel).
However, in case of NB distribution the PDS and AMS models gives the same variance of q(T) when variance (σ2) is 1.5 times the mean number of annual exceedance above threshold.
The methods and results presented here may be useful to those investigating the potential for offshore wind energy development using stochastic process theory to study wind speed or power production since stationary stochastic models provide simpler and more accessible predictions of quantities such as probabilities of exceedance of threshold values, upcrossing rates, and residence times.
However the similarities in the shape of the distributions suggest that, the model may show some skill when looking at the probability of negative events (exceedance of threshold).
The PDS model assumes a Generalized Pareto (GP) distribution for modeling the flood exceedances above threshold corresponding to a generalized extreme value (GEV) distribution for annual maxima.
However both the models perform similarly at higher return periods more than 300 years, using the ratios of the variance of T-years estimase an an index, and the ratio decreases with an increase in mean number of annual exceedances above threshold.
