Exponential family(指数分布族)是一个经常出现的概念,但是对其定义并不是特别的清晰,今天好好看了看WIKI上的内容,有了一个大致的了解,先和大家分享下.本文基本是WIKI上部分内容的翻译. 1. 几个问题 什么是指数分布族? 既然是”族“,那么族内的共同特点是什么? 为何指数分布族被广泛应用?是指数分布族选择了我们,还是我们选择了指数分布族?(这个问题没有回答,需要结合具体实例分析) 2. 参考 Exponential family. (2015, February 26).…

Largest exponential Comparing two numbers written in index form like 211 and 37 is not difficult, as any calculator would confirm that 211 = 2048 < 37 = 2187. However, confirming that 632382518061 > 519432525806 would be much more difficult, as both…

原来国外有个源码(TechnicalAnalysisEngine src 1.25)内部对EMA的计算是: var copyInputValues = input.ToList(); for (int i = period; i < copyInputValues.Count; i++) { var resultValue = (copyInputValues[i] - returnValues.Last()) * multiplier + returnValues.Last(); return…
