News

bizicount 1.3.2

Major

• None

Minor

• Added terrorism data from associated journal article. Can be accessed by the object called terror which is lazily loaded upon loading the package.

bizicount 1.3.1

Major

• None

Minor

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

bizicount 1.3.0

• 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

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.

bizicount 1.1.0

Minor

• Fixed improper univariate distribution aliasing in documentation (#1)
• Added more badges to readme.md (#4)
• Pointed BugReports link to correct GitHub location (#5)
• Added new test to prevent #6 from happening again.

Major

• Fixed fatal error that occurred when the first marginal distribution was zero-inflated, while second margin was not (#6).
• Fixed error when trying to use NumDeriv to get hessian if NLM hessian failed (#8).
• Added a parameter to bizicount() that scales continuous covariates automatically for users (#7).

bizicount 1.0.0

The first release of the package, support for Gaussian and Frank copulas, zero-inflated and non-inflated Poisson and negbin distributions. Extended DHARMa and texreg generics for bizicount and zicreg objects.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
