Titel:
Analyzing model robustness via distortion of the stochastic root: A Dirichlet prior approach 
Abstract:
It is standard in quantitative risk management to model a random vector X of consecutive log-returns in order to ultimately analyze the probability law of the accumulated return. By the Markov regression representation, see [Rüschendorf, de Valk (1993)], any model for X can be decomposed into a vector U of i.i.d. random variables - accounting for the randomness in the model - and a multivariate function f - representing the economic reasoning behind. For most models, f is known explicitly and U...    »
