It is that five models are used to predict China's logistics total output value. The first is linear analysis based on China's GDP between 1978 and 2006. Next, four time-series models constructed using the same time range. Predictions of the logistics total output value from each of the 5 models are compared using actual data from years 2007-2009.The Holt-Winters non-seasonal model gives the least error between actual value and predicted values.
