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.https://github.com/r-universe/chse-ohsu/actions/runs/41288784750Fri, 02 Oct 2026 21:44:10 GMTstaggR0.2.2successhttps://chse-ohsu.r-universe.devhttps://github.com/chse-ohsu/staggrstaggR.RmdstaggR.htmlstaggR2025-09-24 20:20:062026-09-22 19:05:18
