Sieve Maximum Likelihood Estimation for Doubly Semiparametric Zero-Inflated Poisson Models

For nonnegative measurements such as income or sick days, zero counts often have special status. Furthermore, the incidence of zero counts is often greater than expected for the Poisson model. This article considers a doubly semiparametric zero-inflated Poisson model to fit data of this type, which...
