Calculation method
Calculation method
Taxon rate comparisons
[taxon,A rate,B rate,B−A rate,absolute count difference]; rates use supplied effort units.
Presence agreement fraction
Fraction rows where both observers agree on presence versus absence; no detection-probability inference.
Symbols and units
- a
- Paired surveys [taxon ID,observerA count,observerB count,A effort,B effort]
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Paired survey observations, effort, taxa. Returns Agreement and observed detection differences. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification.
