At a glance:Compute N1, N2, N3, N4, Shannon, Evenness from N1, N2, N3, N4. Free online Hong Kong ecology calculator.
Formula
H = -\sum_{i=1}^{S} p_i \ln p_i, \quad p_i = \dfrac{n_i}{N}
J = \dfrac{H}{\ln S}
$$H = -\sum_{i=1}^{S} p_i \ln p_i, \quad p_i = \dfrac{n_i}{N}$$$$J = \dfrac{H}{\ln S}$$How to Use
- Enter N1.
- Enter N2.
- Enter N3.
- Enter N4.
- The calculator returns N1, N2, N3, N4, Shannon, Evenness.
