  3. Fork the repository and make your change on a branch.
  4. Open a pull request that references the issue number.

Research direction

Use the distribution checklist in the issue as the starting point, focusing on the unchecked entries and the sections distinguishing modifiers from distributions implemented in PyMC but not PreliZ. No source files, tests, or implementation entry points are named, so completion criteria and the relevant code locations need to be established before work begins.
