Deprecated. Use mdid instead.
MDiD is a legacy two-period wrapper for the Mean
Difference-in-Differences estimator. The modern replacement
mdid uses a yname/gname/tname
interface and supports staggered treatment adoption natively.
Usage
MDiD(
formla,
xformla = NULL,
t,
tmin1,
tname,
data,
panel = FALSE,
se = TRUE,
idname = NULL,
alp = 0.05,
probs = seq(0.05, 0.95, 0.05),
iters = 100,
retEachIter = FALSE,
biters = NULL
)Arguments
- formla
formula of the form
y ~ treat.- xformla
optional one-sided covariate formula (unused in this estimator; accepted for consistency with other wrappers).
- t
post-treatment period.
- tmin1
pre-treatment period.
- tname
name of the time column.
- data
data.frame.
- panel
logical; whether data are panel.
- se
logical; whether to compute bootstrap SEs.
- idname
name of the unit id column (required when
panel = TRUE).- alp
significance level.
- probs
quantile grid.
- iters
bootstrap iterations.
- retEachIter
logical; return per-iteration results.
- biters
alias for
iters; takes precedence if supplied.
