附录：混合模型对时间异质性的控制的公式推导与数据模拟附录：混合模型对时间异质性的控制的公式推导与数据模拟
为了清楚的解释为什么在处理面板数据时”LSDV增加了虚拟变量λ_t×Time就可以来控制时间的异质性”这个问题，本文首先将数据分为简单数据和复杂数据两种类型，其中简单数据主要是指仅包括时间这一组间变量。例如对十年中国国民幸福感的面板数据，就是针对中...

混合模型对时间异质性的控制
我们从简单到复杂来论述这个问题为什么LSDV增加了虚拟变量λ_t×Time就可以来控制时间的异质性。我 们先来考虑最简单的情况就是时间是唯一的群聚。然 后再考虑复杂的情况，就是面板数据的混合模型所用的情况，这种情况下数据中除了时间之外，还有其他的群�...
