Non-stationary time series analysis and long-term forecasting based on the combination model of wavelet transform and mean-generating function period extrapolation;

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.

With enhanced expectation of Renminbi appreciation,short-term foreign debt in China has increasingly enlarged.

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.
