Calculation method
Calculation method
Standardized card rates
[location,period,count per exposure-day].
Location rate trends
Compare first and last observed period rates; descriptive monitoring only, no treatment advice.

- Card observations [location ID,period index,count,exposure days]
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
- Card observations, exposure days, locations. Returns Standardized counts and trends; no treatment advice. 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.
