WebWe use our method to estimate the marginal expected shortfall θp with (a, b, an) = (0 ⋅ 3, 0 ⋅ 75, 0 ⋅ 85) on each window, for which we get ˆγ ≥ 1 when fitting a generalized Pareto distribution model to the 50 greatest water heights. Figure 1 shows the estimates ˆθp. WebFor a given very small value of p > 0, the marginal expected shortfall (MES) is defined as E(X Y > QY (1−p)), where QY (1−p) is the (1−p)-th quantile of the distribution of Y . The MES is an important factor when measuring the systemic risk of financial institutions. For a wide nonparametric class of bivariate distributions, we ...
