多元线性回归分析在工业洗涤机械行业发展趋势预测中的应用

指出了工业洗涤机械行业发展趋势量化预测的必要性，提出了回归分析在行业发展趋势预测中的应用步骤，建立了我国工业洗涤机械发展趋势预测的多元线性回归模型。在模型讨论中，利用经济学中的需求函数，提炼出解释变量。根据大量调查数据，利用Excel统计软件进行了相关分析、回归分析和统计检验。最后，运用所建立的多元线性回归预测模型对工业洗涤机械行业在2004年的需求量进行了预测。

Application of Multiple Linear Regression Analysis in Prediction of Development Trends for Industry of Industrial Washing Machine

The necessity of quantitative prediction of development trends of Industry of Industrial Washing Machine (IIWM) is pointed out, and the procedure for application of multiple liner regression in this prediction of development trend of industry is put forth. The Multiple Linear Regression Model (MLRM) for prediction of development trends of IIWM is established. In model discussion, explanatory variables are determined by using Demand function of Economics. On the basis of data obtained from practical investigation, correlation analysis, regression analysis and statistical test are carried out by using Excel. Finally, the demand of IIWM at 2004 is predicted by using established MLRM.
