WebbSince diversity corresponds to a low value of D and lack of diversity corresponds to a high value, it is better to use 1 – D, which is called Simpson’s index of diversity. This index takes values between 0 and 1. Another measure is Simpson’s reciprocal index of diversity, which is defined as 1/D. This index takes values between 1 and k.
