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
)
