关于遍历扩散的多步MLE过程

On Multi-Step MLE-Process for Ergodic Diffusion

Yury A. Kutoyants

摘要:

本文提出了一种新的构造渐近有效估计量的方法--过程渐近等价于极大似然估计,同时计算更简便。我们假设所观察的过程是遍历扩散的,并且存在一个长度相对于整个观察时间可以忽略的学习时间间隔。学习时间后获得的初步估计,然后在一步和两步MLE过程的建设。我们讨论了所提出的估计程序的应用程序,其他几个观测模型的可能性。

英文摘要:

We propose a new method of the construction of the asymptotically efficient estimator-processes asymptotically equivalent to the MLE and the same time much more easy to calculate. We suppose that the observed process is ergodic diffusion and that there is a learning time interval of the length negligeable with respect to the whole time of observations. The preliminary estimator obtained after the learning time is then used in the construction of one-step and two-step MLE processes. We discuss the possibility of the applications of the proposed estimation procedure to several other observations models.
