We describe the problem of mining possibilistic set-valued rules in large relational tables containing categorical attributes taking a finite number of values. An example of such a rule might be “IF HOUSEHOLDSIZE={Two OR Tree} AND OCCUPATION={Professional OR Clerical} THEN PAYMENT_METHOD={CashCheck (Max=249) OR DebitCard (Max=175)}. The table semantics is supposed to be represented by a frequen...

The asymptotic behavior of the recovery probability for the dual renewal risk model with constant interest and debit force is studied. By means the idea of Markov Skeleton method, we studied the times that the random premium incomes happened and transformed the continuous time model into a discrete time model. By investigating the fluctuations of this discrete time model, we obtained the asympt...

Since the beginning of the last crisis, financial entities have made an important effort on managing the different aspects of risk. So, different adjustments (XVA) on risk–free derivative value are now included in derivative contracts. In particular, the credit value adjustment (CVA) refers to the increment on the price of a contract due to the possibility of default of one (or both) of the par...
