1、第32卷第3期深圳大学学报理工版Vo1.32No.32015年5月JOURNALOFSHENZHENUNIVERSITYSCIENCEANDENGINEERINGMav2015【数学/Mathematics】基于市道轮换模型的SHIBOR市场利率柳向东,郭慧暨南大学统计学系,广州510632摘要:基于固定波动率模型和广义自回归条件异方差(generalizedautoregressiveconditionalheteroske.dasticity,GARCH)模型,研究引入马氏市道轮换模型.该模型可以将线性利率期限结构推广到非线性形式,运用到资产定价的变化中,特别是债券收益率的
2、确定中.不同于唯一依赖利率水平的传统模型,马氏市道轮换模型能够模拟货币政策对利率的影响.利用2006.10-08至2013-03-29每周三上海银行间同业拆放利率(Shanghaiinterbankofferedrate,SHIBOR)月度数据,用R语言实现并比较了固定波动率模型、GARCH模型以及混合GARCH马氏市道轮换模型对各参数的估计效果.结果表明,混合GARCH马氏市道轮换模型的拟合效果在各种情形下均占优.关键词:应用统计数学;马氏市道轮换;广义自回归条件异方差;上海银行间同业拆放利率;利率期限结构;固定波动率;单机制模型中图分类号:O211.9;F830文献标志码:
