# Source and derivation

`rr-panel.csv` is a four-column trim of `RR-processed.dta` from Thomas Herndon,
Michael Ash and Robert Pollin's deposit at Zenodo:

The derivation keeps `Country`, `Year`, `dRGDP` and `debtgdp`; drops rows in
which either `dRGDP` or `debtgdp` is missing; renames the columns to `country`,
`year`, `growth` and `debtgdp`; converts year to an integer; sorts by country and
year; and rounds growth and debt/GDP to four decimal places. The result contains
1,175 country-years from 20 countries, covering 1946 through 2009.

The shipped CSV is 31,992 bytes. Its SHA-256 is
`4ae80c5bccc03a0ac749ccead53e2d6c36ff755d50a75e7cc5e3c0f985b71191`.

As a decode check only, the retained rows were compared with Vincent Arel-Bundock's
independent CSV export of the same panel. All 1,175 `(country, year)` keys matched,
both rounded numeric columns matched exactly, and there were no missing-value
mismatches. The mirror was not redistributed and is not the licence basis.

The full AGPL-3.0-only text is in `LICENSE-AGPL-3.0.txt` beside the data. The
analysis source is the unminified `../debt-growth-threshold.js` served with this
file.
