This article selects the sales data of a store that somewhere a down jacket from January 2001 to December 2007, through the R language for data processing and analysis, using the Holt - Winters exponential smoothing method to fitting and forecasting of time series, through the prediction error of time curve and histogram, Holt - Winters exponential smoothing method for the sales data of down jacket store provides a suitable prediction model. It provides decision-making information for the later operation and sales of the store.
time series analysis, Holt - winters prediction, auto correlation
