Which distribution is used to model the occurrence of rare events?
Poisson distribution
3.12. The Poisson distribution is used to describe the distribution of rare events in a large population. For example, at any particular time, there is a certain probability that a particular cell within a large population of cells will acquire a mutation.

What do you mean by Rare Event Modeling?
Rare event modeling (REM) refers to efforts to characterize the statistical distribution parameters, generative processes, or dynamics that govern the occurrence of statistically rare events, including but not limited to high-impact natural or human-made catastrophes.
Which is an example of a rare event?
Examples are insurance fraud, major stock market crashes, and disease epidemics. Predicting and simulating such events is difficult but can be extremely valuable. Key challenges are typically the lack of historic data and inapplicability of common statistical techniques.
Is there a problem with logistic regression for rare events?
Although King and Zeng accurately described the problem and proposed an appropriate solution, there are still a lot of misconceptions about this issue. The problem is not specifically the rarity of events, but rather the possibility of a small number of cases on the rarer of the two outcomes.
Which is a rare event in linear regression?
Linear Regression with Rare Events Rare event: No rule of thumb, but Any disease is considered a rare event. Any event as frequent as a disease can be considered rare.Depends on time unit:
