Poissonsaapumisia
Poissonsaapumisia is a hypothetical concept in statistics and marine ecology that describes a class of fish-arrival patterns that superficially resemble a Poisson process but are generated by more complex underlying mechanisms. The term is used in thought experiments and teaching to illustrate how Poisson-based models can be misled by hidden structure in arrival data.
Characteristics include apparent Poisson-like counts with occasional bursts or lulls; inter-arrival times that show overdispersion or
In practice, recognizing Poissonsaapumisia signals the need for more flexible models. Analysts might compare Poisson, negative
Applications lie in fisheries management, acoustic telemetry data analysis, and ecological forecasting, where assuming a simple
Etymology is informal: the name fuses Poisson-based reasoning with a constructed term for arrivals; the concept
