match.data
outputs matched data sets from
matchit()
.match.data(object, group="all", distance = "distance",
weights = "weights", subclass = "subclass")
matchit
. This is
a required input."all"
(all
matched units), "treat"
(matched units in the treatment
group), and "control"
(matched units in the control
group). The default is "all"
."distance"
."weights"
."subclass"
.matchit()
, with just the matched units. The data set also
contains the additional variables distance
, weights
,
and subclass
. The variable distance
gives
the estimated distance measure, and weights
gives the
weights for each unit, generated in the matching procedure.
The variable subclass
gives the subclass
index for each unit (if applicable).
