Simpson Reciprocal
Compute the reciprocal Simpson diversity as one divided by the Simpson concentration.
Description
Compute the reciprocal Simpson diversity as one divided by the Simpson concentration.
Simpson Reciprocal is a focused biology tool that compute the reciprocal Simpson diversity as one divided by the Simpson concentration. It calculates locally from the values you enter and exposes the result without changing the source observations.1
When to use Simpson Reciprocal
Use Simpson Reciprocal when you need to compute the reciprocal Simpson diversity as one divided by the Simpson concentration. Enter Simpson concentration using the definitions and units below so the result can be reproduced.
- Simpson concentration
- A finite measured or assumed value.
How Simpson Reciprocal calculates the result
The published tool contract uses this rule: Compute the reciprocal Simpson diversity as one divided by the Simpson concentration.
- Reciprocal Simpson diversity
- The calculated reciprocal simpson diversity.
Limitations of Simpson Reciprocal
A ratio or percentage can conceal the scale of its numerator and denominator and becomes sensitive to measurement error when the denominator is small.
Alternative or Complementary measurements
Retain the original Simpson concentration values and their units alongside the result. Simpson Evenness is useful when you instead need to compute Simpson evenness as (1 / D) divided by species count from a Simpson concentration index strictly between zero and one. Simpson Index D provides another view by helping you compute the Simpson diversity index D for three species counts in a sample.
