Major

• None

Minor

bizicount 1.3.1 (2023-03-17)

Major

• None

Minor

• There was a warning in R-CMD-CHECK on generic method consistency, which was fixed.

bizicount 1.3.0 (2022-12-02)

• Deprecated scaling parameter, as there is no reliable way to scale covariates properly when transformations and interactionsare introduced to model formulas.

• Deprecated na.action as there are no methods for bizicount that can leverage alternative na.actions other than na.omit.

bizicount 1.2.0 (2022-08-14)

Major

• Add zi_test function to implement tests for zero-modification as found in He et al. (2019).

• Fix bug in scaling parameter where interaction terms would be scaled, not just their constituent covariates.

• Fix bug causing standard error on dependence parameter in Gaussian copula to be incorrect.

Minor

• Change default value of keep parameter in bizicount() function to TRUE so that model matrices, etc., are stored in the output object by default.

• Update documentation with new methods, typo fixes.

• Refactor, add more tests, and minor bug fixes for univariate distribution functions.
