英文摘要:
In this paper, we consider a stochastic asset price model where the trend is an unobservable Ornstein Uhlenbeck process. We first review some classical results from Kalman filtering. Expectedly, the choice of the parameters is crucial to put it into practice. For this purpose, we obtain the likelihood in closed form, and provide two on-line computations of this function. Then, we investigate the asymptotic behaviour of statistical estimators. Finally, we quantify the effect of a bad calibration with the continuous time mis-specified Kalman filter. Numerical examples illustrate the difficulty of trend forecasting in financial time series.

中文摘要:
在本文中,我们考虑一个随机资产价格模型,其中趋势是不可观测的Ornstein-Uhlenbeck过程。我们首先回顾了卡尔曼滤波的一些经典结果。可以预期,参数的选择对于将其付诸实践至关重要。为此,我们得到了封闭形式的可能性,并提供了该函数的两个在线计算。然后,我们研究了统计估计的渐近行为。最后,我们用连续时间错误指定的卡尔曼滤波器量化了错误校准的影响。数值例子说明了在金融时间序列中进行趋势预测的困难。
