WebThe poisson regression model is a great model to reach for anytime you need a simple baseline model for count data. The poisson regression model is simpler than other count-based regression models like zero-inflated poisson, negative binomial, and zero-inflated negative binomial and it has the least parameters to fit. In probability theory and statistics, the Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant mean rate and independently of the time since the … See more The distribution was first introduced by Siméon Denis Poisson (1781–1840) and published together with his probability theory in his work Recherches sur la probabilité des jugements en matière criminelle et en … See more Probability mass function A discrete random variable X is said to have a Poisson distribution, with parameter $${\displaystyle \lambda >0,}$$ if it has a probability mass function given by: where See more As a Binomial distribution with infinitesimal time-steps The Poisson distribution can be derived as a limiting case to the binomial distribution as the number of … See more Applications of the Poisson distribution can be found in many fields including: • Count data in general • Telecommunication example: telephone calls arriving in a system. • Astronomy example: photons arriving at a telescope.
