基于混合Monte Carlo的GARCH模型的贝叶斯估计
Bayesian estimation of GARCH model by hybrid Monte Carlo
摘要:
将混合蒙特卡罗(HMC)算法用于广义自回归条件异方差(GARCH)模型的贝叶斯分析。HMC算法是马尔可夫链蒙特卡罗(MCMC)算法之一,它一次更新所有参数。我们证明了HMC如何正确地再现Gestival参数。该算法具有较强的通用性,可应用于随机波动率模型等其他模型。
英文摘要:
The hybrid Monte Carlo (HMC) algorithm is used for Bayesian analysis of the generalized autoregressive conditional heteroscedasticity (GARCH) model. The HMC algorithm is one of Markov chain Monte Carlo (MCMC) algorithms and it updates all parameters at once. We demonstrate that how the HMC reproduces the GARCH parameters correctly. The algorithm is rather general and it can be applied to other models like stochastic volatility models.
