In bizicount: Bivariate Zero-Inflated Count Models Using Copulas

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.
