Peaks over threshold method
WebAbstract. Two extreme wave analysis models, namely Peaks-Over-Threshold (POT) and Generalized Pareto Distribution (GPD), were developed in order to improve the POT model and highlight merits and limitations of the two models. Studies have shown that the POT model was not equipped with a suitable approach to determine a true threshold value. WebNov 1, 1993 · In the past twenty years a vast new body of extreme value theory was developed, referred to as ‘peaks over threshold modeling.’ This theory allows the use in …
