Bringing this thread back to life as we have begun to scope out what a baseline (name TBD) R package might look like. I think the idea would be that this would act as a sort of companion package to epinowcast, using the epinowcast pre and post-processing but not requiring the installation of Stan.
The hope would for it to be a true baseline multiplicative model, to be used to compare to other methods that might have more extended features e.g. time varying delay estimation, hierarchical delay estimation across groups, weekday effects, or more mechanistic models that estimate latent infections and then apply reporting delays.
@johannes Would love to connect and get any feedback you might have on this proposal now that this post is a few years old. I’ve scoped out some technical specifications in this google doc Baseline Tech Specs - Google Docs
