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. 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
