WebLikewise, a natural way to generalize the parameter of interest (the ATT) from the two periods and two groups case to the multiple periods case is to define group-time average treatment effects: A T T ( g, t) = E [ Y t ( g) − Y t ( 0) G = g] This is the average effect of participating in the treatment for units in group g at time period t. WebOct 16, 2024 · The dashboard does three things. First, it enables varying the parameters of the data generation process. Second, it runs the three main models we have in mind here: event study, regression discontinuity in time (RDiT), and difference-in-differences (DID). And third, it visualizes and compares the estimates coming out of each of these models.
