%description
Provides methods for difference-in-differences with a continuous treatment
and staggered treatment adoption. Includes estimation of treatment effects
and causal responses as a function of the dose, event studies indexed by
length of exposure to the treatment, and aggregation into overall average
effects. Uniform inference procedures are included, along with both
parametric and nonparametric models for treatment effects. The methods are
based on Callaway, Goodman-Bacon, and Sant'Anna (2025)
<doi:10.48550/arXiv.2107.02637>.
