Estimation of the nearly unit root processes with GARCH errors and a drift(带有GARCH误差和趋势项的近单位根过程的估计)
近单位根过程在时间序列理论中占有重要地位.因其处于平稳过程与非平稳过程(单位根过程)的中间地带,研究其统计性质的重要价值在于揭示这个中间地带的特殊属性,及其与平稳过程和单位根过程统计属性的差异.在更新项只有二阶矩存在的条件下,讨论了带有GARCH(p,q)误差项与趋势项的近单位根过程的最小二乘估计.并推导了基于最小二乘估计的Dickey-Fuller检验统计量的渐近分布.该结果在单位根检验中具有一定意义....
