Evaluating relatively stable points by dividing-into-group regression based on dummy variables;
基于虚拟变量的分段回归探寻相对稳定点
The daily power consumption was sectionized according to its characteristics of value changing with time and temperature and corresponding dummy variables were imported.
介绍了线性回归分析中虚拟变量的概念和意义,根据日用电量随时间和温度变化的特性,将其分段并引入相应的虚拟变量,在此基础上建立电量预测的回归模型,并以南京市2002年至2004年日用电量为样本进行预测检验,预测结果表明了该方法的有效性。
The intercept and slope of dummy variable model do not remain constant ,but the variant of parameter is discrete but not continuous.
尽管在虚拟变量模型中,使回归模型的截距或斜率不再是固定不变的,但参数的变化是离散的,而不是连续的。
