A Cardinality Matched Dataset for the Lalonde (1986) Data
Description
Data from Lalonde (1986) and two matched datasets: One where optimal 1:1 propensity score matching was used, and one where cardinality matching was used, with the balance constraint that all standardized covariate mean differences be below 0.1.
Usage
data(lalondeMatches)
Format
240 units (rows) and 10 variables (columns). The columns are:
-
treat
: A binary treatment variable. Equal to 1 if treated in the National Supported Work Demonstration; equal to 0 otherwise. -
age
: age in years. -
educ
: years of education. -
black
: an indicator variable, equal to 1 only if the subject is black. -
hispan
: an indicator variable, equal to 1 only if the subject is hispanic. -
married
: an indicator variable, equal to 1 only if the subject is married. -
nodegree
: an indicator variable, equal to 1 only if the subject does not have a degree. -
re74
: earnings in 1974. -
re75
: earnings in 1975. -
subclass
: The subclass denoting the pairs within the matched dataset.
Details
The cardinality matched datset was produced using the designmatch
R
package.
