Web14 Apr 2024 · By incorporating prior beliefs about the distribution of the data and the costs of different outcomes, an asymmetric loss function can help to improve the accuracy and efficiency of Bayesian inference. Varian proposed an asymmetric LF named LLF. The LLF is preferred to mitigate the risk related to the Bayes estimator. It is defined as follows:
Web1 Nov 2012 · Value-at-Risk (VaR) was pioneered in 1993, as a part of the “Weatherstone 4:15pm” daily risk assessment report, in the RiskMetrics model at J.P Morgan.
