Steps to replicate matching analysis:

1. Place the file QJPS_activekssentences.dta in the matching directory.

2. Run QJPS_create_datasets_for_matching.do in STATA from the progfiles subdirectory. This discards all observations for which there are no exact matches on discrete criteria in both treatment and control groups, and then creates separate datasets for unchallenged only, as well as datasets for use in the discontinuity analysis. All datasets are saved in Stata format in the matching directory.

3. Run QJPS_main_matching_analysis.R in R 2.4.1 or higher from the progfiles subdirectory.

The matching application generates a log file for the data pre-processing, and a log file for the matching analysis. These can find found in the logfiles subdirectory.
