Extreme TLDR:
Explore the Poisson distribution for modeling count data in cases like online marketplaces, sports, and queuing. Understand its formula, assumptions, and when to use it, while considering limitations like overdispersion. Extensions include time-varying and mixed Poisson distributions to address real-life deviations. Aim for simplicity or Bayesian models for inference.
