Various ratings of certification can be gained with RRR being the highest rating. A team at cascad rerun the code using appropriate software. Currently SAS, Matlab, Mathematica, R, Python, Stata, Fortran, C++ are supported.
on confidential data within restricted mexico rcs data data environments, checking results becomes much more complicated. Indeed, Lars had told us that some 40% of in economics papers use restricted data, and that these are exempt from standard journal reproducibility checks.
