In this paper, we present a full velocity difference model for a car-following theory based on the previous models in the literature. To our knowledge, the model is an improvement over the previous ones theoretically, because it considers more aspects in car-following process than others. This...
我们的目标就是找到最好的θ，使差分趋近于0，从机器学习的角度，G是V(s)的Ground Truth/Label. 这个学习过程无需对p(•|s,a)建模即Model-Free。 TD(0)one-step Temporal-Difference，过程如下：one step 是针对Excepted Return的估计来说的，只考虑当前Action的Reward，未来的Rewards由V近似。以上是个...
The application of the difference-in-difference model to the analysis of the policy impact of the General Tariff on British industry has provided new insights. Refining the tariff classification into three groups adds value to the analysis of UK tariffs during the 1930s, allowing us to distinguish...
pydynpd: A python package for dynamic panel model pydynpd is the first python package to implement Difference and System GMM [1][2][3] to estimate dynamic panel data models. Below is a typical dynamic panel data model: In the equation above, x is a predetermined variable that is potential...
while controlling for time-invariant differences between treated and untreated states and for time-varying exogenous factors (i.e., those that affect both treated and untreated states equally). The classic DID specification is generally implemented as a two-way fixed effects model that includes both...

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...
