A Semiparametric Approach to Test for the Presence of INAR: Simulations and Empirical Applications
The present paper explores the application of bootstrap methods in testing for serial dependence in observed driven Integer-AutoRegressive (models) considering Poisson arrivals (P-INAR).

Multilevel Modeling on Underdispersion Data [PDF]
Binomial negative regression is able to handle poisson regression problem with underdispersion assumption. When the data has hierarchy and level that need to be calculated, regression is no longer appropriate to solve this problem, therefore binomial ...

Generalised Poisson Distributions for Modelling Parity [PDF]
Conventional parametric count distributions, namely the Poisson and Negative-Binomialmodels, do not offer satisfactory descriptions of empirical distributions of completed cohortparity.

Flexible models for overdispersed and underdispersed count data [PDF]
AbstractWithin the framework of probability models for overdispersed count data, we propose the generalized fractional Poisson distribution (gfPd), which is a natural generalization of the fractional Poisson distribution (fPd), and the standard Poisson distribution.

Generalised score distribution: underdispersed continuation of the beta-binomial distribution
AbstractConsider a class of discrete probability distributions with a limited support. A typical example of such support is some variant of a Likert scale, with a response mapped to either the $$\{1, 2, \ldots , 5\}$$ { 1 , 2 ,

On Arbitrarily Underdispersed Discrete Distributions
We survey a range of popular generalized count distributions, investigating which (if any) can be arbitrarily underdispersed, that is, its variance can be arbitrarily small compared to its mean. A philosophical implication is that some models failing this simple criterion should not be considered as “statistical models” according to McCullagh’s ...
