摘要 结合国外研究现状,对解决多维GARCH模型的方法———Factor-GARCH模型进行了系统的讨论.将投资组合的收益率Rt表述为潜在公共因子的函数形式,并对函数形式中的一些变量和假定给出了理论和现实的解释;将投资组合的协方差Ht的结构进一步细化,将其表述为可观测变量的线性函数.并指出了今后的研究方向. Integrating with international studies, this paper introduces in detail Factor-GARCH model which solves the estimation of multi GARCH model, and discusses it all-around. The paper puts rhe yield of portfolios to express as the function of latent common factors. And the paper points out the trend of study in the future.
