The Poisson process is a stochastic model in probability theory for random events in time or space, such as call arrivals in telecommunications or disease spread in epidemiology. It includes homogeneous and non-homogeneous types, with applications in finance, insurance, ecology, and more. The process aids in predicting event occurrences and assessing risks, with advanced concepts expanding its use across multiple domains.

The Poisson process is a stochastic process used to model random events over time or space
Independence of Events
The Poisson process assumes that events occur independently of each other
Constant Mean Rate
The Poisson process assumes that events occur at a constant mean rate
The Poisson process is used in various fields such as telecommunications and epidemiology to model discrete events with continuous intervals between occurrences
The homogeneous Poisson process assumes a constant rate of event occurrence
The non-homogeneous Poisson process allows for a varying rate of event occurrence
The compound Poisson process incorporates variability in the magnitude of each event
The Poisson process can be used to model sales transactions in a store for inventory management and sales forecasting
The spatial Poisson process is used to model the random distribution of organisms in a region for ecological studies
The compound Poisson process is used in finance and insurance to model irregular events with varying magnitudes
The Poisson point process is used to model the spatial distribution of points in various fields such as telecommunications and astronomy
The non-homogeneous Poisson process is particularly useful for modeling events with rates that vary over time, such as rush-hour traffic or seasonal customer demand in retail
