The bizicount R-package is primarily for estimating copula-based bivariate count regression models, with and without zero-inflation or overdispersion. However, its full suite of functions can:
Estimate copula-based bivariate zero-inflated count regression models, as well as non-inflated models.
Estimate univariate zero-inflated count models (zic.reg)
Carry out post estimation diagnostics using the DHARMa package (simulate.bizicount, simulate.zicreg, make_DHARMa)
Produce professional tables in latex, word, or plain-text using the texreg package (extract.bizicount, extract.zicreg).
Test for zero modification using zi_test() (He et al. 2019).
Evaluate univariate zero-inflated count distribution CDFs, PDFs, and quantile functions, and generate random zero-inflated counts (pzip or pzinb, dzip or dzinb, qzip or qzinb, and rzip or rzinb)
