Then we derive the asymptotical distribution of the extended moment estimator and prove its asymptotically normality.
因此得到了推广矩估计量的渐近分布，于是证明了推广估计量的渐近正态性。
Finally, the asymptotical distribution of the smoothing estimator related to the extended moment estimator is derived by the study of process before.
最后根据对前面过程的研究得到了推广矩估计量的平滑估计量的渐近分布。
