In the process of material flow, business sales plan is a very important issue. Determine the sales down, purchase and other indicators can be determined accordingly, so accurately predict the sales of the year is to do a good job in material management an important part. How to predict the sales volume then? There are many ways, but the regression method to predict the sales method is simple and easy to grasp. Regression prediction predicts the direction and degree of change of another dependent variable (Y) based on the change of one independent variable (x), which can be analyzed by both time series analysis and causal analysis. Combined with material sales forecast requirements, here only for the time series
