Pushing Rust projects to Deta can require cross-compiling or timeout during the build process. Compiling on a Linux runner on GitHub Actions and pushing the artifact can solve both of these issues.
I provide a simple example of a Dirichlet regression in PyMC. This form of generalized linear model is appropriate when modeling proportions of multiple groups, that is, when modeling a collection of positive values that must sum to a constant. Some common examples include ratios and percentages.
