Parameter estimation of the generalized Pareto distribution—Part II

Abstract: This is the second part of a paper which focuses on reviewing methods for estimating the parameters of the generalized Pareto distribution (GPD). The GPD is a very important distribution in the extreme value context. It is commonly used for modeling the observations that exceed very high thresholds. The ultimate success of the GPD in applications evidently depends on the parameter estimation process. Quite a few methods exist in the literature for estimating the GPD parameters. Estimation procedures, such as t… Show more

“…The POT approach uses the GP distribution as a model to assign probabilities to the exceedances of E over a predefined threshold, i.e. to values E = E − E min (with E > E min ), where E min is a prescribed minimum value (de Zea Bermudez and Kotz, 2010). The GP cumulative distribution function of exceedances E is…”

“…Several approaches have been proposed involving different techniques to rate indices of fire danger against fire history over a given period and study area. Examples of such techniques include logistic regression and percentile analysis (Andrews et al, 2003), cluster analysis (Dymond et al, 2005) and threshold setting based on a geometric progression (Van Wagner, 1987) or on values of probability (DaCamara et al, 2014). Fire history traditionally consists of ground observations of fire occurrence (Anderson and Englefield, 2001), fire load (Merrill and Alexander, 1987), suppression difficulty (Kiil et al, 1977) and area burned (San-Miguel-Ayanz et al, 2012).…”

“…The selection of u is a selection over a univariate rv, and so any of the standard methods from the literature on univariate EVT for selecting the value of u may be employed, such as plots, mean-excess plots, etc. [11] While there is typically a region of in which u results in stable estimates of the GPD shape parameter ξ, making such univariate explorative techniques useful, useful, there is scope for Bayesian estimation of this threshold, for which the interested reader is directed to the surveys [8, 34, 35], which are mostly based on non-deterministic approximations, such as those involving MCMC.…”

“…The most common methods to estimate the unknown parameters of the GP distribution are the following: (i) the maximum likelihood (ML) method [15]; (ii) the method of moments [16]; (iii) the method of probability weighted moments [17]; (iv) the least squares (LS) method [18]; (v) the elemental percentile method [19] and (vi); the Bayesian technique, proposed by Castellanos and Cabras [20]. Bermudez and Kotz [21] made a review of the above-mentioned estimation methods. The selection of threshold is critical for the accurate estimation of the parameters of the GP distribution and in turn, return levels.…”
