In order to do so, compare the free energy of a perfectly ordered system with the free energy of a partially disordered case that introduces the less energetic frustrations
Using both the Wiener chaos expansion on the systemic economic factor and a Gaussian ap- proximation on the associated truncated loss, we significantly reduce the computational
This means that the asset value goes down more often either when systemic factor has negative values with higher weight, or when the marginal default probability is
Because the state of the economy is widely driven by macroeconomic factors, Credit Portfolio View proposes a methodology to connect these macroeconomic factors
Referring back to our discussion on the third type of benchmark in the introduction, we would expect a physical model to be better at simulating the more complex Q E compared to
After giving some expla- nations about the capillarity (physical justification and purpose, motivations related to the theory of non-classical shocks (see [28])), we prove
We can thus perform Bayesian model selection in the class of complete Gaussian models invariant by the action of a subgroup of the symmetric group, which we could also call com-
Consider a one-period (1 year) binomial market model (B, S) consisting of a bond, paying an annual risk-free rate of r = 4% and a risky asset, with current spot price S 0 = 100. In
