Description

A optimal 1:1 propensity score matched dataset for the Lalonde (1986) dataset.

Usage

data(lalondeMatches)

Format

370 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 optimal 1:1 propensity score matched dataset was produced using the MatchIt R package. The propensity scores were estimated using logistic regression, where treat was the outcome and the other variables were the covariates (within no interactions included).
