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. WebDID is typically used to estimate the effect of a specific intervention or treatment (such as a passage of law, enactment of policy, or large-scale program implementation) by comparing the changes in outcomes over time between a population that is enrolled in a program (the intervention group) and a population that is not (the control group).
