Description:
Maximum likelihood estimation of copula-based zero-inflated (and non-inflated) Poisson and negative binomial count models. Supports Frank and Gaussian copulas. Allows for mixed margins (e.g., one margin Poisson, the other zero-inflated negative binomial), and several marginal link functions. Built-in methods for publication-quality tables using 'texreg', post-estimation diagnostics using 'DHARMa', and testing for marginal zero-modification via . For information on copula regression for count data, see Genest and Ne
