Two demos are provided which use this dataset. The first,
`DehejiaWahba`

, replicates one of the models from Dehejia and
Wahba (1999). The second demo, `AbadieImbens`

, replicates the
models produced by Abadie and Imbens
https://scholar.harvard.edu/imbens/scholar_software/matching-estimators.
Many of these models are found to produce good balance for the Lalonde
data.
