APPLETSOURCEDESCRIPTION
Forecasting by SmoothingA Collection of JavaScript E-labs Learning Objects (Arsham)For series with up to 80 observations, calculates forecasts and errors using: moving averages and weighted moving averages for specified period, single, double and triple exponential smoothing for specified alpha value, and Holt's linear smoothing for specified alpha and beta.  more
Exponential SmoothingCAPDM Tutorial AppletsFor a specific data set, shows differences as smoothing constant is varied, also shows differences in moving averages as period is varied.  more
Forecasting AppletMcGraw-HillUsers can view, adjust or add points to the example series or enter up to 20 observations of their own data, can employ exponential smoothing or trend adjusted exponential smoothing with various smoothing constants, or use the linear trend equation or simple linear regression and observe forecasts, MAD, and MSE.  more
Statlets, Exponential SmoothingStatgraphics onlineCreates plots using simple, linear, quadratic, or Holt's linear smoothing for sample data or user-entered/imported data, user can adjust smoothing constants to observe effects on forecasts and MAPE.   more
