Sum of rank ratios: an alternative to percentiles for research assessment, from groundbreaking to mainstream research

Alonso Rodriguez-Navarro

The Rn index sums ten local-to-global rank ratios to better measure each country's highest-quality research than top-percentile counts.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The Rn index using 10 rank ratios is a better option than the number of top 10 per cent or top 1 per cent highly cited papers for evaluating the highest quality science produced by each country.

C2weakest assumption

That citation rank ratios summed over the first 10 papers accurately reflect the highest quality science without requiring external validation against other quality indicators or expert judgment.

C3one line summary

Rn index sums the first ten local-to-global rank ratios of citation-ranked papers to assess country-level research quality as an alternative to percentile counts.
