Hey @SamuelBrand1, here is one you could take! I also suggest: #17!
Hey @SamuelBrand1, I know the issue says "[t]his does not include code, just specification of the feature in math/writing," but I would argue that it is a good idea to include coding. In my view, coding stuff helps with the thinking process of theory too, and it makes sense to include the coding and documentation at the same time. What do you think?

As a reference to https://github.com/cdcent/cfa-multisignal-renewal/discussions/104#discussioncomment-9374461, this issue deals with the implementation of a stochastic generation interval (i.e. for inference). The GI used in the hospital admissions-only version of the WW project uses a deterministic quantity.

Just to clarify about the generation interval: you're saying that for now, you're not going to try to estimate the GI in the model. Instead, you're just going to pass in a vector $\vec{v}$ where entries represent the probability mass of the discretized GI for integer delays of $d$ days.
If so, this is also how we're doing it in our $R_t$ model, so I think this is totally sufficient for now.
Goal
We want to have a single source of truth for the mathematical formulation of the generation interval probability mass function for flu and COVID. We want to be able to use this to immediately code up the math decided upon here.
Context
This was discussed in the 2024-02-27 meeting (see minutes) and agreed upon in the ADR record under
model_features.md
. This specific feature should be the same as what's implemented in the existing wastewater model. Completion of this task will allow us to implement the feature more quickly and should facilitate creation of a model design document.Required features
