Fitting Component-Specific-Proportionally Constrained Zero-Inflated Generalized Additive Models with Discrete Responses

Description

COZIGAM.dis fits a COZIGAM with component-specific-proportional constraint for discrete zero-inflated exponential family responses, e.g. Poisson and binomial distributions. If the regular exponential family admits 0 as a possible realization with positive probability, the EM algorithm is used in the estimation procedure.

COZIGAM.cts fits a COZIGAM with continuous zero-inflated exponential family responses. One of the two funcions is called from cozigam automatically depending on the distribution family if the argument constraint="component".
