Bivariate Distributions via Conditional Specification

Implementation of bivariate binomial, geometric, and Poisson distributions based on conditional specifications. The package also includes tools for data generation and goodness-of-fit testing for these three distribution families. For methodological details, see Ghosh, Marques, and Chakraborty (2025) , Ghosh, Marques, and Chakraborty (2023) , and Ghosh, Marques, and Chakraborty (2021) .

BCD

The R package BCD provides core functions for the implementation of bivariate binomial, geometric, and Poisson distributions based on conditional specifications. The package also includes tools for data generation and goodness-of-fit testing for these three distribution families. See Ghosh et al. (2025), Ghosh et al. (2023), and Ghosh et al. (2021).
