We propose a fast algorithm for computing the expected tranche loss in the Gaussian factor model with arbitrary accuracy using Hermite expansions. No assumptions about homogeneity of the portfolio are made. The algorithm is a generalization of the algorithm proposed in \cite{PO}. The advantage...

We provide a fast algorithm to calculate the m-dimensional distance histogram on which Brock, Dechert, and Sheinkman's (1987) BDS-type statistics are based. The algorithm generalizes a fast algorithm due to LeBaron by calculating the histogram for any finite set of distances simultaneously, and...

Исследованы зависимости между ковариационными матрицами, вычисляемыми в процессе многомерной рекурсии Левинсона. Показано, что учет выявленных взаимосвязей...

Active credit portfolio management is becoming a central part of capital and credit management within the banking industry. Stimulated by the Basel II capital accord the estimation of risk sensitive credit and capital management is central to success in an increasingly competitive environment....

While Pillar 1 of the regulatory capital framework Basel II stipulates capital requirements for credit, market and operational risk, Pillar 2 focuses on the economic and internal perspective of banks’ capital adequacy. To ensure capital adequacy, banks are required to have an Internal Capital...
