针对经济时间序列的特点，研究了时间序列在小波变换下的不同分解成分，提出了基于小波分析的时间序列分解及重构模型；在此基础上，给出了小波预测方法。 - The real runoff time series was divided into the high frequency item and the low frequency item with the help of the wavelet analysis first , then the two items were modeled by chaos theory and the stepwise regression algorithm , at last the output of the two models were added together .
论文首先借助小波分析，将实测径流时间序列分解为高频项和低频项两项，其次对这两项分别用混沌理论和逐步回归理论建模，其中混沌预报借助基于自组织法求解的的volterra级数来完成，然后将两者结果叠加起来。 - The paper decomposes the visitor ' s flow sequence made of different frequencies into the low and high frequencies in the multi - resolution analysis according to the characteristic of visitor ' s flow sequence frequencies and then restores the trend components according to the reconstruct principle of wavelet coefficients , in order to deduce the visitor ' s flow trend
