标准布朗运动随机采样下最小二乘估计的极限分布

Limit distribution of the least square estimator with observations sampled at random times driven by standard Brownian motion

Tania Roa, Soledad Torres, Ciprian tudor

摘要:

在这篇文章中,我们研究了最小二乘估计的极限分布,适当的归一化,从回归模型中的观察被假定为有限的($αN$)和两个不同的随机时间下采样。基于特征函数的极限性质和收敛性结果,证明了最小二乘估计的渐近正态性。我们目前的模拟结果来说明我们的理论结果。

英文摘要:

In this article, we study the limit distribution of the least square estimator, properly normalized, from a regression model in which observations are assumed to be finite ($αN$) and sampled under two different random times. Based on the limit behavior of the characteristic function and convergence result we prove the asymptotic normality for the least square estimator. We present simulation results to illustrate our theoretical results.
