  • Li Identifiability of zeroinflated Poisson models

  • One well-known zero-inflated model is Diane Lambert's zero-inflated Poisson model, which concerns a random. Zero-inflated poisson regression is used to model count data that has an excess of zero counts.

    Further, theory suggests that the excess zeros are generated by.

    1. The second process is governed by a Poisson distribution that generates counts, some of which may be zero.
