Important Developments in Soliton Theorycally rigorous and operationally superior and granular credit risk measures such as probability of default (PD). This paper reverse-engineers a mapping methodology converting PDs to letter ratings by referencing the realized default rates of different rating categories experienced by a commercial rating agency such as standard & Poor’s or Moody’s.

SpringerBriefs in Molecular Scienced. The fact that there have been many successful applications of this idea seems to indicate that there must be a fundamental reason for selecting this particular family of distributions. In this paper, we show that the selection of this family can indeed be explained if we make reasonable invariance requirements.

Wolfgang Pahlitzsch,Hubert BühneExtreme value theory has emerged as one of the most important statistical disciplines for the applied sciences. In this paper, the extremal properties of univariate alpha-skew-normal distribution was discussed. In addition, asymptotic tail dependence coefficients of the bivariate alpha-skew-normal distribution are investigated.

We constructed a recommender network in which the trust relationship is derived from a social network viewpoint and found that the trust relation is measured more appropriate by group interactions in the SN than by using individual interactions.
