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

, qzip
or qzinb
, and
