The main objective of this paper was to illustrate derivation of Heckman-Conway-Maxwell-Poisson ‘HeckCOMPoisson’ model. HeckCOMPoisson model is an integrated model from Heckman and Conway-Maxwell-Poisson model. HeckCOMPoisson was developed to handle count model with selection. The model perform perfectly in terms of Goodness-of-Fit (GOF) and in prediction of count data with selection and handling under-dispersion and over-dispersion experienced in count data. HeckCOMPoisson distribution is flexible and gives robust models for dispersed counts.
