look at the problem of calibrating financial models, measuring the model uncertainty of a claim and choosing an optimal … uncertainty. Using the framework for market risk measures we propose axioms for new classes of model uncertainty measures. Similar … to the market risk case, we prove representation theorems for coherent and convex model uncertainty measures. Example …

In this thesis, we try to provide a broadeconometric analysis of a class of risk measures, distortion risk measures (DRM). With carefully selected functional form, theValue-at-Risk (VaR) and Tail-VaR (TVaR) are special cases of DRMs. Besides, the DRM also admits interpretation in the sense...

This approach can cope … with heterogeneous error distributions and is proven to hold asymptotically. In simulation studies factor based bootstrap … inference outperforms the wild bootstrap and pairs bootstrap approach according to its size features. Regarding current account …

In survival analysis, proportional hazards model is the most commonly used and the Cox model is the most popular. These models are developed to facilitate statistical analysis frequently encountered in medical research or reliability studies. In analyzing real data sets, checking the validity of...
