On arbitrarily underdispersed discrete distributions
You are welcome to attend the following joint La Trobe statistics and stochastic seminar.
- Thursday 28 April 2022 12:00 pm until Thursday 28 April 2022 01:00 pm (Add to calendar)
- Andriy Olenko
- Presented by:
- Dr Alan Huang, UQ
- Type of Event:
We review a range of generalized count distributions, investigating which (if any) can be arbitrarily underdispersed, i.e., its variance can be arbitrarily small compared to its mean. A philosophical implication is that models failing this criterion perhaps should not be considered a “statistical model” according to the extendibility criterion of McCullagh (2002). Four practical implications will be discussed. We suggest that all generalizations of the Poisson distribution be tested against this property.
