Using propensity scores in difference-in-differences models to estimate the effects of a policy change. Health Serv. Outcome Res. Methodol. 2014;14(4):166-182.Stuart EA, Huskamp HA, Duckworth K, et al. Using propensity scores in difference-in-differences models to estimate the effects of a...
In this article, we consider identification, estimation, and inference procedures for treatment effect parameters using Difference-in-Differences (DiD) with (i) multiple time periods, (ii) variation in treatment timing, and (iii) when the “parallel trends assumption” holds potentially only after ...

We explain when and how staggered difference-in-differences regression estimators, commonly applied to assess the impact of policy changes, are biased. These biases are likely to be relevant for a large portion of research settings in finance, accounting, and law that rely on staggered treatment ...
is the film with pre-stress. For the without pre-stress case, it seens fine that the charge value to the two methods is very close (Error < 0.2%). Strange thing appears in the case with pre-stress, the charge value obtained by the two method...
In this model, or indeed with any generalized linear model, the interaction is still a difference in differences estimate — but not of the means, but rather of the means transformed by the link function. In the case of a logistic model, it estimates the difference in differences of log od...
Knowing the difference between rendering and 3D modeling can also help you understand the workflow involved in both processes, which can lead to more information about costs and time estimates of specific projects. 3D modeling and 3D rendering are two consecutive stages of the same process. However...
If explicit information on the source of heterogeneity is available, it may be possible to account for study-level differences in the modeling, but in the absence of such information a useful and simple way to express study-level heterogeneity is with a random-effects or hierarchical model: (3...
