Extreme-value based estimation of the conditional tail moment with application to reinsurance rating

Insurance: Mathematics and Economics. 107:102-122
Several risk measures have been proposed in the literature, among them the marginal mean excess, defined as MME_p = \mathbb E[(Y^{(1)}-Q_1(1-p))_+|Y^{(2)}> Q_{2}(1-p)], provided \mathbb E|Y^{(1)}|< \infty, where (Y^{(1)}, Y^{(2)}) denotes a pair of r

We propose a nonparametric robust estimator for the tail index of a conditional Pareto-type distribution in the presence of censoring and random covariates. The censored distribution is also of Pareto-type and the index is estimated locally within a

The marginal expected shortfall is an important risk measure in finance, which has been extended recently to the case where the random variables of main interest (Y^{(1)}, Y^{(2)}) are observed together with a covariate X\in \mathbb R^d. This leads t

We propose a robust estimator of the stable tail dependence function in the case where random covariates are recorded. Under suitable assumptions, we derive the finite dimensional weak convergence of the estimator properly normalized. The performance

In the context of bivariate random variables $\left (Y^{(1)},Y^{(2)}\right )$ , the marginal expected shortfall, defined as $\mathbb {E}\left (Y^{(1)}|Y^{(2)} \ge Q_{2}(1-p)\right )$ for p small, where Q2 denotes the quantile function of Y(2), is an

We consider the local estimation of the stable tail dependence function when a random covariate is observed together with the variables of main interest. Our estimator is a weighted version of the empirical estimator adapted to the covariate framewor
