Maximum likelihood estimation of copula-based zero-inflated (and non-inflated) Poisson and negative binomial count models, based on the article doi:10.18637/jss.v109.i01. 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 doi:10.1177/0962280217749991. For information on copula regression for count data, see Genest and Nešlehová (2007) doi:10.1017/S0515036100014963 as well as Nikoloulopoulos (2013) doi:10.1007/978-3-642-35407-6_11. For information on zero-inflated count regression generally, see Lambert (1992) https://www.jstor.org/stable/1269547. The author acknowledges support by NSF DMS-1925119 and DMS-212324.
