摘要：
In multivariate analysis, the least square method is often used multiple linear regression model. However, the least squares estimation is sometimes far from ideal, this case of resulting is the dependent variable often exist the strong collinearity. This paper discusses the principles of the principal component regression and calculation steps and we use the real-time data of the Jingdezhen City Chongyang Cement Industrial Co., Ltd. to create the model predict it.
