The Smoothed Moving Average displays data for a given period of time (N). The formula for calculating this average is as follows: SMMA(i) = (SUM(i-1) – SMMA(i-1) INPUT(i))/N where the first period is a simple moving average. See also Simple Moving Average....
The large sample formula gives a result that is close to the bootstrap procedure, except at very sparse frequencies.doi:10.1007/s11135-009-9231-1Dougal HutchisonNFERspQuality & QuantityHutchison D. The standard error of moving average smoothed equipercentile equating. Qual Quant 2010; 44: 783-...
Ito's formulaThis article is concerned with the problem of selecting a suitable bandwidth when estimating the marginal density function of a moving average process. The smoothed bootstrap method is used to implement a bandwidth selector for a convolution-type density estimator, based on the kernel...

2.2 Effective Elastic Moduli For more effective discussion, we first brief on the standard formulation of FEM in numerical homogenization [14, 15], as some of these formulae will be used repetitively in later sections. In the homogenization, two levels of coordinate systems are used: one is ...
The present paper considers which models must be applied to smoothed data when models of moving average type or autoregressive models have been introduced for the instantaneous variables. A result of the simple formulae derived is to give a warning against use of simple models for the smoothed ...
Reference values are expressed in SI units in the formulae. 4.3. Influence of the Particle Shape The impact of a cubic particle was investigated for different orientations towards the wall, thus leading to a study of the impact of different geometrical features summarized in Figure 7. In ...

Equation (38) is, however, only true if the water surrounding the WEC is standing still, which is no longer the case when the WEC is moving in waves. In the formula of the drag force, the relative velocity difference has to be used, which is the difference between the WEC’s velocity...
The weighted average rule is used to obtain the equivalent nodal stress in the smoothing domain, and the shape function interpolation technique is used to obtain the continuous stress field in the problem domain. The process is similar to the FEM. Finally, the accuracy of the results is assesse...
