Combining two forecasts, this study compares two most popular combining methods such as simple average and weighted average methods from theoretical angles. The standard deviation of the combined forecast error is quantified as a function of the ratio of standard deviation and the correlation ...
Moving average is of three types, simple weighted and exponential. In this article, we will explain the methods to calculate all three types of moving averages inExcel. Read:How to use MIN, Max, and AVERAGE Functions of Excel. How to calculate Moving Average in Excel We will calculate the...
Weighted Moving Average A weighted moving average is simply an average whose weights are calculated in an arbitrary way which is not that of SMA or EMA. There are no rules as to how the values can be assigned, although it is always very important to know (at least roughly) what ...
1) simple average and weighted optimum combination principle 最优加权组合 1. The paper presents a short term load combined forecasting model using thesimple average and weighted optimum combination principles. 文中分别应用简单平均组合与最优加权组合原理,建立了短期负荷预测的组合模型。
the gross PTI is compiled through a two-stage process: firstly the pay adjustment data for larger companies and those for smaller companies are consolidated separatelyonasimpleweightedaveragebasis, and secondly these two figures are combined to produce the gross PTI by applying a gross-up factor of...

英语翻译Moving averageOne,very simple,method for time series forecasting is to take a moving average (also known as weighted moving average).The moving average (mt) over the last L periods ending in period t is calculated by taking the average of the values for the periods t-L+1,t-L+2...
If we replace ℓtℓt with ^yt+1|ty^t+1|t and ℓt−1ℓt−1 with ^yt|t−1y^t|t−1 in the smoothing equation, we will recover the weighted average form of simple exponential smoothing. The component form of simple exponential smoothing is not particularly useful, but it...
