Abstract: | This paper studies asymptotic normality of the composite quantile regression estimation of the drift function for diffusion model.Based on discretely observed 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 proposed is verified. |

Keywords: | diffusion model drift function composite quantile regression estimation asymptotic normality |
