必应词典为您提供exponentially-weighted-moving-average的释义,un. 指数加权移动平均数;
ExponentiallyWeightedMovingAverage实现了EWMA,它是线程安全的;其构造器要求输入alpha及initialAvg;alpha越大表示新数据权重越大旧数据权重越小 getAverage返回的是averageBits的值,不过它存储的是double的bit形式,返回的时候使用Double.longBitsToDouble转换会double addValue方法使用(alpha * newValue) + ((1 - alpha) *...
第五部份:EWMA (Exponentially Weighted Moving Average)指数加权移动平均控制图 一、数据随时间变化的权重 二、EWMA图的特点 1、特点 (1)EWMA图对过程位置的稍小变动十分敏感。 (2)EWMA图的每一点都综合考虑了前面子组的信息。 (3)对过程位置的大幅度移动EWMA图没有XBA图敏感。 (4)EWMA图可以应用于单值,也...
The EWMA can be calculated for a given day range like 20-day EWMA or 200-day EWMA. To compute the moving average, we first need to find the corresponding alpha, which is given by the formula below: Where: N= number of days for which the n-day moving average is calcula...

Exponentially Weighted Moving Average (EWMA) plans for negative binomial counts with a non-homogeneous (time-varying) mean are developed for monitoring disease counts. These plans are used to identify unusual disease outbreaks or unusual epidemics. Time-varying means are typical for disease counts. ...
