Labour Training Evaluation Data
nswdemo data frame contains 722 rows and 10 columns.
These data are pertinent to an investigation of the way that
earnings changed, between 1974-1975 and 1978, for an experimental
treatment who were given job training as compared with a control
group who did not receive such training.
psid1 data set is an alternative non-experimental "control"
psid3 are subsets of
designed to be better matched to the experimental data than
psid1. Note also the
datasets (DAAGxtras) that have been proposed as
