1. 2 固定效应模型fixed-effect model 和随机效应模型random-effects model 就是所有省份,既有相同的部分,即斜率项都相同;也有不同的部分,即截距项不同。 2.1 固定效应模型 fixed-effect model yit=ai+bxit+ᵋit cov(ci,xit)≠0 1. 固定效应方程隐含着跨组差异可以用常数项的不同刻画。每个ai都被视为未...
举例:假设有i个变量,则需要添加i-1个个体效应误差项即可,这种做法是为了避免多重共线性。 那少添加的那个变量的个体效应是不是就被舍去了呢?答:并不是。 因为还有截距项 0,所以一共正好有i个截距项,正好一一对应 时间效应同上 三、固定效应模型fixed effects model (一)总体思路:减去组内平均值 (二)具体操作...
