Shannon Entropy and Herfindahl-Hirschman Index as Team's Performance and Competitive Balance Indicators in Cyclist Multi-Stage Races. [PDF]

Thus, in this paper, I use (i) the Shannon intrinsic entropy (S) as an indicator of “teams sporting value” (or “competition performance”) and (ii) the Herfindahl-Hirschman index (HHi) as a “teams competitive balance” indicator, in the case of (professional) cyclist multi ...

Some notes on applying the Herfindahl–Hirschman Index [PDF]
Applied Economics Letters, 2011 The Herfindahl–Hirschman Index is one of the most commonly used indicators to detect anticompetitive behaviour in industries.
