Πώς να υπολογίσετε το Biodiversity Index (Shannon)

Τι είναι το Biodiversity Index (Shannon);

The Shannon-Wiener diversity index H' measures biodiversity combining species richness and evenness. H' = −Σ(pᵢ × ln pᵢ).

Οδηγός βήμα προς βήμα

1. 1pᵢ = nᵢ/N for each species
2. 2H = −Σ(pᵢ × ln pᵢ)
3. 3H_max = ln(S) · Evenness J = H/H_max
