2.3.4.2. Peaks over threshold models (POT). The POT model is gen-erally considered to be the most useful for practical applicationsdue to the more efficient use of the data for the extreme values. Inthis model, we can distinguish between two types of analysis: (a)the fully Parametric models based on the Generalised Pareto dis-tribution (GPD) and (b) the Semi-parametric models built aroundthe Hill estimator.
