主要研究扩散模型中漂移函数的复合分位回归估计的渐近正态性.基于离散观测样本,利用复合分位回归的方法得到了漂移参数函数的局部估计量,并证明了估计量的渐近正态性.
This paper studies asymptotic normality of the composite quantile regression estimation of the drift function for diffusion model. Based on discretely ohserved sample of the diffusion models, the local estimation of the drift parametric functions are gained by using composite quantile regression method, and the asymptotic normality of the estimation that we pro- posed is verified.
