This repository contains code and results for a simulation study examining the performance of Poisson regression models under violations of the equi-dispersion assumption (mean = variance).

We present a method to obtain both exact values and sharp estimates for the total variation distance between binomial and Poisson distributions with the same mean λ. We give a simple efficient ...

Abstract: Within Markowitz's mean-variance framework, the portfolio selection problem is proposed on finite time horizon [0,T] . Unlike with the classical continuous-time mean-variance portfolio ...

For binomial and Poisson distributions, the scale parameter has a value of 1. The variance of Y is for the binomial distribution and for the Poisson distribution. Overdispersion occurs when the ...

Abstract: New lower bounds on the total variation distance between the distribution of a sum of independent Bernoulli random variables and the Poisson random variable (with the same mean) are derived ...
