Delaporte

Delaporte is an R package which provides the probability mass, distribution, quantile, random variate generation, and method of moments parameter estimation functions for the Delaporte distribution. As the distribution does not have a closed form, but requires summations or double summations to calculate values, the functions have been programmed in Fortran and C. In cases where approximations are sufficient, the quantile and random variate generator have the option to use a much faster Poisson-negative binomial estimate as opposed to the full Delaporte double summations.

Submission

If you would like to contribute to the project, it may be prudent to first contact the maintainer via email. A request or suggestion may be raised as an issue as well. To supply a pull request (PR), please:

  1. Fork the project and then clone into your own local repository
  2. Create a branch in your repository in which you will make your changes
  3. Ideally use -s to sign-off on commits under the

Developer Certificate of Origin. 4. If possible, sign commits using a GPG key. 5. Push that branch and then create a pull request

At this point, the PR will be discussed and eventually accepted or rejected by the lead maintainer.

Roadmap

Major

  • There are no plans for major changes at current.

Minor

  • There are no plans for minor changes at current.

Security

Expectations

This package is a calculation engine and requires no secrets or private information. It is checked for memory leaks prior to releases to CRAN using ASAN/UBSAN. Dissemination is handled by CRAN. Bugs are reported via the tracker and handled as soon as possible.

Assurance

The threat model is that a malicious actor would "poison" the package code by adding in elements having nothing to do with the package's purpose but which would be used for malicious purposes. This is protected against by having the email account of the maintainer—used for verification by CRAN—protected by a physical 2FA device (Yubikey) which is carried by the lead maintainer.
