Definitive Proof That Are Zero Inflated Poisson Regression
The Poisson probability mass function, with rate parameter μi, is given by: where, yi is the number of under-five deaths the ith mother in a given time with rate parameter μi, the mean and variance of the Poisson distribution is given as E(Y) = Var(Y) = μ. Once a count is determined to be non-zero, the regular Poisson process takes […]
