首先需要指出:PLM所谓的固定效应FE,在本文讨论的所有统计模型中是唯一的一个有点“名不副实”的术语——因为即使在FE的PLM里面,个体效应也依然是「异质」而非真正「固定为同一个值」的(陈强, 2014《高级计量经济学及Stata应用》)。换句话说,在PLM里面,无论FE还是RE,个体截距(相当于HLM里面Level 2不同组各自的...

where d1 is 1 when i=1 and 0 otherwise, d2 is 1 when i=2 and 0 otherwise, and so on. d1, d2, ..., are just dummy variables indicating the groups, and v1, v2, ..., are their regression coefficients, which we must estimate. ...

Given persistent concerns regarding the role of confounding and omitted variables described earlier (Baumrind et al., 2002, Larzelere et al., 2017), our study used fixed effect regression analysis. This analytic method makes use of repeated measures in longitudinal data and essentially allows every ...
