Introduction to VaR (Value-at-Risk)

The concept of Value-at-Risk is described. We discuss how this risk characteristic can be used for supervision and for internal control. Several parametric and non-parametric methods to measure Value-at-Risk are discussed. The non-parametric approach is represented by historical simulations and Monte-Carlo methods. Variance covariance and some analytical models are used to demonstrate the param...

T he study by Ang et al. (1) in this issue of PNAS strikes a precautionary note, in that it presents experimental evidence that prolonged continuous ultrasound (US) exposure may cause mild disruption in neuronal migration to the cerebral cortex in fetal mice. The authors (1) suggest that such neuronal heterotopia may result in anomalies in brain circuitry and synaptic activity. Does this study ...
