Calculation method
Calculation method
Group encounters per km
Sum observations / total distance for each group.
Total effort (km)
Sum surveyed distances; counts are observations, not unique population estimates.
Symbols and units
- a
- Transects [group ID,observed count,distance km]
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
- Observations, surveyed distance, effort groups. Returns Encounter rates and effort totals. 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.
