英文摘要:
We consider a self-exciting counting process, the parameters of which depend on a hidden finite-state Markov chain. We derive the optimal filter and smoother for the hidden chain based on observation of the jump process. This filter is in closed form and is finite dimensional. We demonstrate the performance of this filter both with simulated data, and by analysing the `flash crash\' of 6th May 2010 in this framework.

中文摘要:
我们考虑一个自激计数过程,其参数依赖于一个隐有限状态马尔可夫链。基于对跳跃过程的观察,我们推导了隐藏链的最优滤波器和平滑器。这个滤波器是封闭的,是有限维的。我们通过模拟数据和在该框架下分析2010年5月6日的“闪电崩溃”来证明该滤波器的性能。
