By using exponential Splines model, we estimate the bond's term structure of Shanghai stock exchange, then we have a static analysis to it and obtain the statistical feature of term structure.
At the same time, this paper utilizes the improved model based on exponential regressive curve and ARMA model to carry on the medium and long-term electric power demand forecasting in Hunan province.
同时本文利用指数曲线与ARMA的叠加预测模型对湖南省中长期电力需求进行了具体的实证研究。
