基于非时齐扩散模型的离散观测样本,利用局部近似的方法,构造了扩散系数的局部估计量,并证明了估计量的强相合性和渐近正态性.
Based on discretely observed sample of the time-inhomogeneous diffusion models, the local estimation of the diffusion coefficient is proposed by using local approximate method. Furthermore, we verify the strong consistency and asymptotic normality of the local estimation proposed.
