QDiD

Description

Deprecated. Use qdid instead.

QDiD is a legacy two-period wrapper for the Quantile Difference-in-Differences estimator. It accepts a formula and explicit t/tmin1 time period arguments. The modern replacement qdid uses a yname/gname/tname interface and supports staggered treatment adoption natively.

Usage

QDiD(
  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,
  pl = FALSE,
  cores = NULL,
  biters = NULL,
  cl = NULL
)

Arguments

formla	formula of the form y ~ treat.
xformla	optional one-sided covariate formula.
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.
alp	significance level.
probs	quantile grid.
iters	bootstrap iterations.
retEachIter	logical; return per-iteration results.
pl	logical; parallel bootstrap.
cores	number of cores.
biters	alias for iters; takes precedence if supplied.
cl	alias for cores; takes precedence if supplied.

Value

QTE object.
