Let be a popularity degree of a block is defined as the future access frequency based on the number of access demand, at a time, the popularity degree of a block can be calculated using Holt's Linear and Exponential Smoothing

For instance, analysts forecasting metrics that exhibit a time-series trend might utilize exponential smoothing
or regression models.
AWO utilizes powerful forecasting algorithms, including Box-Jenkins ARIMA, exponential smoothing
, Seasonal Regression, and Transfer Function Method to provide superior accuracy.
For the entire year, exponential smoothing
predicted total revenues within 3 percent five times, and two of those times were within 1 percent.
The continuous research (Dzikevicius, Saranda 2010) was the first academia research of using TA to predict the values for OMX Baltic Benchmark Index and compare it with S&P 500 Index of US using an exponential smoothing
method--the exponential moving average (further--the EMA).
Research (Teunter & Sani, 2009) explains that many companies use single exponential smoothing
to forecast intermittent demand, but this generally leads to inappropriate stock levels and Croston's forecasting method (CR) proves to be appropriate and it takes account of both demand size and inter-arrival time between demands.
also discuss techniques such as time series-moving average, exponential smoothing
, and trending.
They are based on various statistical methods such as regression [2-3], Box Jenkins model , exponential smoothing
 and Kalman filters .
The results using the Holt-Winters exponential smoothing
technique are reported in case 3 and are similar economically; however, the point estimate of the coefficient is less significantly different from zero in a statistical sense using the change in the exponential smoothing
estimate of productivity growth.
Those techniques include jury of executive opinion, sales force composite, customer expectations, decomposition, exponential smoothing
, moving average, regression analysis, simulation, straight-line projection, Box-Jenkins time series models, expert systems, neural networks, trend line analysis, and life cycle analysis.
D200A has four different techniques available to forecast these demands, including an 8quarter moving average, a 4-quarter moving average, simple exponential smoothing
, and a regression technique known as predictive logistics.
