Labour Training Evaluation Data
Description
The 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.
The psid1
data set is an alternative non-experimental "control"
group. psid2
and psid3
are subsets of psid1
,
designed to be better matched to the experimental data than
psid1
. Note also the cps1
, cps2
and cps3
datasets (DAAGxtras) that have been proposed as
non-experimental controls.
