staggR - Fit Difference-in-Differences Models with Staggered
Interventions
Fits linear difference-in-differences models in scenarios
where intervention roll-outs are staggered over time. The
package implements a version of an approach proposed by Sun and
Abraham (2021) <doi:10.1016/j.jeconom.2020.09.006> to estimate
cohort- and time-since-treatment specific
difference-in-differences parameters, and it provides
convenience functions both for specifying the model and for
flexibly aggregating coefficients to answer a variety of
research questions.
