英文摘要:
The R package stochvol provides a fully Bayesian implementation of heteroskedasticity modeling within the framework of stochastic volatility. It utilizes Markov chain Monte Carlo (MCMC) samplers to conduct inference by obtaining draws from the posterior distribution of parameters and latent variables which can then be used for predicting future volatilities. The package can straightforwardly be employed as a stand-alone tool; moreover, it allows for easy incorporation into other MCMC samplers. The main focus of this paper is to show the functionality of stochvol. In addition, it provides a brief mathematical description of the model, an overview of the sampling schemes used, and several illustrative examples using exchange rate data.

中文摘要:
R包stochvol在随机波动性框架内提供了异方差建模的完全贝叶斯实现。它利用马尔可夫链蒙特卡罗(MCMC)采样器进行推理,从参数和潜在变量的后验分布中获取数据,然后用于预测未来的波动率。该软件包可以直接用作独立工具;此外,它可以方便地并入其他MCMC采样器中。本文的重点是展示stochvol的功能。此外,它还提供了模型的简要数学描述、所用抽样方案的概述,以及使用汇率数据的几个示例。
