1. 在STATA 12中构建DCC-MGARCH模型的第一步是确保已经安装了相应的STATA程序包，可以通过net install命令来安装。2. 启动STATA后，应先加载所需的MGARCH工具包，使用命令`use mgarch`。3. 在选择模型类型时，应指定为DCC模型。在命令窗口输入`garch model`，然后选择`dcc`选项。4. 设定好模型参数...
DCC-GARCH（DynamicConditional Corelational Autoregressive Conditional Heteroscedasticity Model）用于研究市场间 波动率 的关系。接下来我们按照GARCH族模型的发展历程来梳理一遍 研究对象：波动率的时间序列，即研究当期波动率与上一期波动率之间的关系。常用于存在波动急剧现象的时间序列，最简单关系的就是线性...
A Study on the Spillover Effect of P2P Lending Interest Rate Based on DCC-GARCH Model Xu Yunsong (Postdoctoral Program,Central University of Finance and Economics,Beijing 100081) Abstract:As the core of price system of internet financial market,the spillover effect of P2P lending interest rate ...
The DCC-GARCH model is typically estimated using maximum likelihood estimation. The likelihood function is given by: `。 L(\theta) = -\frac{1}{2} \sum_{t=1}^T \left[\log|Q_t| + R_t'Q_t^{-1}R_t \right] `。 where: θ is the vector of model parameters. T is the number...
这里的关键问题是 Mean Model (这里是 ARMA(1,1) 模型)和 GARCH Model, 这里 sGARCH(1,1) 基本上是 GARCH(1,1) 的模型。 点击标题查阅往期内容 R语言多元动态条件相关DCC-MVGARCH、常相关CCC-MVGARCH模型进行多变量波动率预测 ...
