用STATESPACE过程研究寄生蚤与其宿主关系

Research the relations between parasitic fleas and their host by using STATESPACE process

基于调查自内蒙古土默特平原的原始数据 ,编写SAS语言程序 ,建立了多元时间序列模型 .结果得到模型值与实测值拟合较好。

We established the time series model by writing SAS program and using original data.The result showed the model values could fit the real measure values with small errors, proved stability of the model equilibrium state, and exited time delay phenomenon of the relation between the flea index and their host's density.
