%description
Testing for parallel trends is crucial in the Difference-in-Differences
framework. To this end, this package performs equivalence testing in the
context of Difference-in-Differences estimation. It allows users to test
if pre-treatment trends in the treated group are “equivalent” to those in
the control group. Here, “equivalence” means that rejection of the null
hypothesis implies that a function of the pre-treatment placebo effects
(maximum absolute, average or root mean squared value) does not exceed a
pre-specified threshold below which trend differences are considered
negligible. The package is based on the theory developed in Dette &
Schumann (2024) <doi:10.1080/07350015.2024.2308121>.
