Full textAtmospheric dispersion of contaminated clouds following deliberate or accidental releases of CBRN (chemical, biological, radiological, nuclear) toxic substances may have serious health impacts. In order to estimate them, CBRN risk assessment activities rely, among other things, on atmospheric dispersion models. These models compute the concentration field of pollutant in order to quantify potential adverse effects on human population. They need to be evaluated, which means their outputs have to be compared to experimental data within an appropriate methodology. Now, existing evaluation methodologies have two flaws: firstly they are not suited to risk assessment, and secondly their results may be somewhat arbitrary because they are based on direct comparisons between observations and model results. Turbulence in the atmospheric boundary layer introduces a large random component in the observations, and thus an inevitable gap between observations and model results, be the latter "perfect". In this thesis two tools have been built to fix these issues. The first one is an evaluation methodology suitable for the risk assessment context. The second one is an empirical statistical model meant to estimate the uncertainty in the simulation results. It can be associated to an atmospheric dispersion model with probabilistic capabilities in order to produce an envelop of the answer rather than a unique "average" result, the latter being of little use despite its omnipresence in current risk assessment studies. When used jointly, the two tools developed in this thesis enable model/experiment comparisons to be more objective and less subject to experimental randomness

Full textIn this thesis, we study the problem of conditional Value at Risk (VaR) estimation taking into account estimation risk and model risk. First, we considered a two-step method for VaR estimation. The first step estimates the volatility parameter using a generalized quasi maximum likelihood estimator (gQMLE) based on an instrumental density h. The second step estimates a quantile of innovations from the empirical quantile of residuals obtained in the first step. We give conditions under which the two-step estimator of the VaR is consistent and asymptotically normal. We also compare the efficiencies of the estimators for various instrumental densities h. When the distribution of is not the density h the first step usually gives a biased estimator of the volatility parameter and the second step gives a biased estimator of the quantile of the innovations. However, we show that both errors counterbalance each other to give a consistent estimate of the VaR. We then focus on the VaR estimation within the framework of GARCH models using the gQMLE based on a class of instrumental densities called double generalized gamma which contains the Gaussian distribution. Our goal is to compare the performance of the Gaussian QMLE against the gQMLE. The choice of the optimal estimator depends on the value of d that minimizes the asymptotic variance. We test if this parameter is equal 2. When the test is applied to real series of financial returns, the hypothesis stating the optimality of Gaussian QMLE is generally rejected. Finally, we consider non-parametric machine learning models for VaR estimation. These methods are designed to eliminate model risk because they are not based on a specific form of volatility. We use the support vector machine model for regression (SVR) based on the least square loss function (LS). In order to improve the solution of LS-SVR model, we used the weighted LS-SVR and the fixed size LS-SVR models. Numerical illustrations highlight the contribution of the proposed models for VaR estimation taking into account the risk of specification and estimation
