基于多元线性回归模型对遵义东贸直营店配件出库量预测和解释

Forecast and Interpretation of Parts Outbound Volume of Zunyi Dongmao Direct Store Based on Multiple Linear Regression Model

配件销售等于服务商内部维修出库加经销商外销出库,考虑数据封闭性、可得性、准确性,本论文聚焦服务商的内部维修出库。通过应用统计学学习,了解到应用统计学可以通过Eviews软件多元回归模型,通过可决系数、F检验,T检验,确定模型的拟合度,因子的显著性,从而可以达到预测配件出库量。

The sale of accessories is equal to the service provider’s internal maintenance out of the warehouse plus the distributor’s export out of the warehouse.Considering the data closure,availability,and accuracy,this paper focuses on the service provider’s internal maintenance out of the warehouse.Through the study of applied statistics,the paper learns that applied statistics can use the Eviews software multiple regression model,through the coeffi cient of determination,F test,and T test to determine the fi t of the model and the signifi cance of the factors,so as to predict the amount of accessories out of stock.
