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 in their Matlab code. Many of these models are found to produce good balance for the Lalonde data.
