Building the prediction model(s) from the historical time series has attracted many researchers in last few decades. For example, the traders of hedge funds and experts in agriculture are demanding the precise models to make the prediction of the possible trends and cycles. Even though many statistical or machine learning (ML) models have been proposed, however, there are no universal solutions available to resolve such particular problem. In this paper, the powerful forward-backward non-linear filter and wavelet-based denoising method are introduced to remove the high level of noise embedded in financial time series. With the filtered time series, the statistical model known as autoregression is utilized to model the historical times aeries and make the prediction. The proposed models and approaches have been evaluated using the sample time series, and the experimental results have proved that the proposed approaches are able to make the precise prediction very efficiently and effectively. 展开更多

文章运用Best Basis Selection(BBS)算法选取最优小波包基,对上证综指收盘价进行小波包非线性阈值消噪,在消除随机性干扰的基础上,针对传统均线策略买卖信号滞后性的不足,根据不同分解水平的小波低频分量能够反映信号基本和次级趋势... 文章运用Best Basis Selection(BBS)算法选取最优小波包基,对上证综指收盘价进行小波包非线性阈值消噪,在消除随机性干扰的基础上,针对传统均线策略买卖信号滞后性的不足,根据不同分解水平的小波低频分量能够反映信号基本和次级趋势且不具滞后性的特点,提出了一种基于小波低频分量的量化择时策略,并对该策略和传统的均线策略分别用R语言进行仿真模拟交易和回测,实验表明在类似风险的情况下,该策略在提示基本和次级趋势买卖信号的同时可以缩短交易信号的滞后性,具有更好的投资表现。 展开更多
