VaR Backtest

创建一个VaR(风险),val模型和俄文n suite of VaR backtests

VaR (value-at-risk) is an estimate of how much value a portfolio can lose in a given time period with a given confidence level. VaR backtesting tools assess the accuracy of VaR models. For more information on VaR backtesting tools, seeOverview of VaR Backtesting.
