WebExcel Data Analysis Tool: Excel provides the Exponential Smoothing data analysis tool to simplify the calculations described above. To use this tool for Example 1, select Data > … Perhaps one of the most confusing aspects of exponential smoothing is the damping factor. Damping factors are used to smooth out the graph and take on a value between 0 and 1. Technically, the damping factor is 1 minus the alpha level (1 – α). But all you really need to know is smaller alpha levels (i.e. larger … See more Exponential smoothing of time series data assigns exponentially decreasing weights for newest to oldest observations. In other words, the older the data, the less priority (“weight”) the data is … See more The basic formula is: St = αyt-1 + (1 – α) St-1 Where: 1. α = the smoothing constant, a value from 0 to 1. When α is close to zero, smoothing happens more slowly. Following this, the best value for α is the one that results … See more If your data shows a trend and seasonality, use triple exponential smoothing. In addition to the equations for single and double … See more This method is deemed more reliable for analyzing data that shows a trend. In addition, this is a more complicated method which adds a … See more

Exponential smoothing is a rule of thumb technique for smoothing time series data using the exponential window function. Whereas in the simple moving average the past observations are weighted equally, exponential functions are used to assign exponentially decreasing weights over time. It is an easily learned and easily applied procedure for making some determination based on prior assumptions by the user, such as seasonality. Exponential smoothing is often used for ana… WebStatistics and Probability. Statistics and Probability questions and answers. 1) Suppose you have decided to implement Single Exponential smoothing on the stock data and you have chosen alpha to be 0.2, what is your damping factor? 2) Fit Single Exponential Smoothing with alpha=0.2. what is the value for MAD?
