Bivariate threshold excess model
WebExtreme value theory is used to model the risk of extreme, rare events, such as the 1755 Lisbon earthquake. Extreme value theory or extreme value analysis ( EVA) is a branch of statistics dealing with the extreme deviations from the median of probability distributions. It seeks to assess, from a given ordered sample of a given random variable ... WebThe choice of a sufficiently large threshold with the application of the bivariate point process entails the same consideration as that used by the threshold excess model. …

Having discussed the block maxima method the last time, we will now have a look at the threshold excess method. According to Coles (2001), the threshold approach is more efficient than the block maxima method if complete (time) … WebThe bivariate-threshold-excess and point process models are appropriate for modelling the markets’ risks. For modelling the extremal dependence however, given the same marginal threshold quantile, the point process has more access to the extreme observations due to its wider sphere of coverage than the bivariate-threshold-excess …
