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
DHARMapackage (simulate.bizicount,simulate.zicreg,make_DHARMa) -
Produce professional tables in latex, word, or plain-text using the
texregpackage (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 (
pziporpzinb,dzipordzinb,qziporqzinb, andrziporrzinb)
