摘要
在包含周期变动的回归预测模型基础上,在趋势分量的估计中引入了多元线性回归估计,并将此模型应用于山东省城镇居民人均生活消费的预测,提高了拟合度和预测精确度.
Based on the regression prediction model with periodic alteration,a multivariate linear regression prediction method to predict the trend component in the model is proposed.The application of the method in predicting urban population's average consume in Shandong Province shows it improves the goodness of fit and prediction precision.
