Poissonmodeller
Poissonmodeller is a term used to describe software tools, libraries, or methodological frameworks for modeling count data using Poisson-based techniques. It typically refers to implementations that fit Poisson and related generalized linear models, provide diagnostic tools, and support extensions for common deviations from the Poisson assumptions.
Such tools normally implement maximum likelihood estimation for Poisson regression with a log link, allow inclusion
Real-world applications include epidemiology (disease incidence), traffic and public safety (accident counts), insurance claim modeling, ecology
Limitations of Poisson-based modelling arise when data exhibit overdispersion, underdispersion, clustering, or temporal and spatial dependence;
