This package includes all the data sets used in the Introductory Econometrics: A Modern Approach by Jeffrey Wooldridge. It is similar to the R package Wooldridge.
To download this package execute:
pkg> add WooldridgeDatasets
Then run
using WooldridgeDatasets
Then use wooldridge("Dataset name") (any of these two), to use the dataset. It'd be better if these commands are used with DataFrame() function from DataFrames.jl package.
If you face any problem, feel free to raise it in the issues.
