Exponential functions are widely used in mathematics and computer science for a variety of applications. In Python, there are several built-in functions and modules that allow us to work with exponential functions efficiently. In this article, we’ll explore the various ways to work with exponentia...

常见的方法就是将该变量视为单变量时间序列。有很多模拟这些序列的方法。例如ARIMA,exponential smoothing,或者Facebook的Prophet,自动回归机器学习方法被越来越多地使用(https://towardsdatascience.com/machine-learning-for-forecasting-transformations-and-feature-extraction-bbbea9de0ac2)。
指数移动平均 (Exponential Moving Average, EMA) 加权移动平均 (Weighted Moving Average, WMA) 双指数移动平均 (Double Exponential Moving Average, DEMA) 三动态移动平均 (Triple Exponential Moving Average, TEMA) 还有一些少见的 TRIMA, KAMA 和 MAMA。公式就不写了,知道它们是一种计算均值的方法就行。
