Poisson Regression

Poisson regression is similar to multinomial logistic regression in that the dependent variable can take only non-negative integer values. With multinomial logistic regression the dependent variable takes takes values 0, 1, …, r for some known value of r, while with Poisson regression there is no predetermined r value, i.e. any count value is possible.
