The wavelet method used in economic forecast depends on its " mathematics microscope " property . it does the layer analysis and forecast to indicators . it can improve forecast precision , what ' s more it can search and express the structural feature of data such as development cycle , second cycle , especially to some sudden change data which will provide effective and reliable warranty to the complexity and violent fluctuant data indicators in enterprise 基于小波进行经济预测的方法依靠其“数学显微镜”的特性,对待分析的预测指标进行逐层分析和预测,在提高预测精度的基础上,能对分析数据对象的结构特征进行挖掘,分析数据特征如发展主周期、次周期等,尤其对具有突变性质的数据具有很好的表征分析能力,这对于企业中复杂的变动剧烈的数据指标的预测能提供有效可靠的保证。
