带有周期漂移自排斥扩散的最小二乘估计
Least Squares Estimation fora Self-Repelling Di?usion withPeriodic Drift
摘要: 本文研究一类由标准布朗运动驱动且带有周期漂移的自排斥扩散模型,若 θ为未知的自排斥参数, L(t)为周期的参数函数,本文的主要目的是讨论当 θ> 0时参数的估计问题。利用 L(t)的周期性与 Frobenius矩阵公式,我们建立了参数的最小二乘估计量,并进一步讨论了该估计量的相合性与渐近分布等渐近行为。
Abstract: In this paper, we consider a self-repelling diffusion model with periodic drift: L(t) is a periodic, parametric function; θ is unknown parameter. The main object of this paper is to study the estimation problem of the parameters when θ> 0. By utilizing the periodicity of L(t) and the Frobenius matrix formula, we have established the least squares estimator of parameters, and we have discussed the asymptotic behavior of the estimator.
