方法总结|相依结构Copula主要方法 Copula作为一种联合分布,具有拟合非线性相关和尾部相关的双重优势,正被广泛运用在金融市场联动性、相关性刻画中,逐渐成为相依结构建模的主流模型。 擅长的Copula方法如下: 1.按变量个数:二元Copula、传统多元Copula、多元藤VineCopula。 2.按时变情况:静态Copula和动态时变Copula,其中动...

They concluded that VaR and CoVaR, based on GARCH-EVT-COPULA, better calculate the exchange rate risk. Gencay and Selçuk (2004) used the peaks over threshold (POT) method to measure the tail risk in emerging markets and the VaR-based Generalised Pareto distribution (GPD) performance. Their...
