bizicount: Bivariate Zero-Inflated Count Models Using Copulas
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>.
