This package produces a simulated dataset and it reproduces on the simulated data all the exhibits in the study "Youth Crime and Delinquency In And Out Of School" by Janine Boshoff, Stephen Machin and Matteo Sandi. This package is for code execution and workflow validation only. It is not intended to reproduce the paper’s original coefficient estimates, sample sizes, or substantive conclusions. The confidential administrative data used for the published results are described in Section 3 of the Read me file. The data used in this study cannot be posted in the EJ repository. Authorised replicators with approved access must replace the synthetic CSV files with the licensed originals (keeping filenames unchanged) and run the code inside the approved secure environment (ONS Secure Research Service).
