In the case that the smoothed values can be written as a linear transformation of the observed values, the smoothing operation is known as a linear smoother; the matrix representing the transformation is known as a smoother matrix or hat matrix. The operation of applying such a matrix transformation is called convolution. Thus the matrix is also called convolution matrix or a convolution kernel.

The simplest of the exponentially smoothing methods is naturally called simple exponential smoothing (SES) 14. This method is suitable for forecasting data with no clear trend or seasonal pattern. For example, the data in Figure 8.1 do not display any clear trending behaviour ... peterson rehabilitation hospitalSimple exponential smoothing does not do well when there is a trend in the data. In such situations, several methods were devised under the name "double exponential smoothing" or "second-order exponential smoothing," which is the recursive application of an exponential filter twice, thus being termed "double exponential smoothing". This nomenclature is similar to quadruple exponential smoothing, which also references its recursion depth. The basic idea beh… peterson redmond oregon

It's estimating the current value, and you're then using that same current value estimate for the prediction (unlike, say, double exponential smoothing where you assume a linear trend -- a nonzero derivative). Thinking in terms of filtering provides insight.
