Non-stationary time series analysis and long-term forecasting based on the combination model of wavelet transform and mean-generating function period extrapolation;
基于小波变换和均生函数周期外推组合模式的非平稳时间序列分析与长期预测
A hybrid prediction approach combining wavelet transform(WT) and mean-generating function period extrapolation(MGFPE) is presented and applied to the long-term prediction of nonlinear time sequences of ship roll motion.
为了获得横摇运动在不同时间尺度下的演变规律,提出了利用小波变换和均生函数周期外推混合模式进行船舶横摇运动非线性时间序列长期预测的方法。
With enhanced expectation of Renminbi appreciation,short-term foreign debt in China has increasingly enlarged.
随着人民币升值预期的加强,短期外债不断增加。
This paper presents a simple theoretic model that account for the abundance of short-term foreign debt in emerging market countries afflicted by currency crises, and argues that the over-inflows of short-term foreign debt in emerging markets result from governments guarantee on private investment.
本文提出一个简单的理论模型来解释新兴货币危机国在危机前存在大量短期外债的原因 ,认为政府对私人投资的担保导致了短期外债大量流入新兴市场国家。
