摘要

本文提出了一种新的短时间序列外推法，可用于经济、环境和地球物理参数的预测。该方法是基于修正有限差分行的性质，即最佳三次逼近在凸性范围内。数值结果表明，与基于多项式的外推方法(包括牛顿外推法)相比，该方法具有显著的优势。

Pyramidal method of extrapolation for short time series

The paper proposed a new method of short time series extrapolation, which can be used for predicting of economic, environmental and geophysical parameters. This method is based on the property of the rows of modified finite differences that the best cubic approximation is in the range of convexity. Numerical results show significant advantages of the proposed method in comparison with approaches to extrapolate, based on the use of polynomials, including Newton's extrapolation.
