Title: Bivariate Zero-Inflated Count Models Using Copulas
Version: 1.3.4

    person("John", "Niehaus", , "jniehaus2257@gmail.com", role = c("aut", "cre"))
Description: 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
