State-level policy evaluations commonly use a difference-in-differences (DID) study design; yet within this framework, statistical model specification varies notably across studies. More guidance is needed about which set of statistical models perform best when estimating how state-level policies affect...
We propose a model that allows the control and treatment groups to have different average benefits from the treatment. The assumptions of the proposed model are invariant to the scaling of the outcome. We provide conditions under which the model is nonparametrically identified and propose an ...
Social behavior in a genetic model of dopamine dysfunction at different neurodevelopmental time points Impairments in social behavior characterize many neurodevelopmental psychiatric disorders. In fact, the temporal emergence and trajectory of these deficits... PA Kabitzke,EH Simpson,ER Kandel,... - 《...

These are the forced swim test, the chronic mild stress and the learned helplessness models, the Flinders sensitive line rats, which is a genetic model of depression and the lipopolysaccharide-induced sickness behaviour, a putative inflammatory model of depression. Collectively, our data have shown ...
, the model included the dog’s name as a random factor, accounting for the covariance of measures taken from the same dog across the episodes of the SST. Post hoc contrasts were computed with Bonferroni correction whenever a significant effect was found for a factor included in the model....
来自问题:什么是双重差分模型(difference-in-differences model)? 双重差分吗,就是差分两次。 我们先来举个栗子。 现在要修一条铁路,铁路是条线,所以必然会有穿过的城市和没有被穿过的城市。记Di=1 如果城市i被穿过,Di=0 如果城市i没有被穿过。 现在我们比较好奇铁路修好以后,被铁路穿过的城市是不是经济增长更...
