This category is for discussion relevant to the development of Epinowcast. This includes the present and future of the core Epinowcast code and its interfaces. --- ## [Adding importation to EpiNow2 and epinowcast](https://community.epinowcast.org/t/adding-importation-to-epinow2-and-epinowcast/235)

Is anyone planning to add a feature to EpiNow2 and epinowcast that would account for imported cases? That would be super useful. Thanks!

This is just a note so I don’t forget - will circle back. All based on work with @sangwoopark with any good bits being theirs and any fever dreams being mine.

As part of the epinowcast 0.2.1 release which many of us have been working away at for a while I gave the website (i.e. epinowcast.org) a lick of paint. The main changes were to introduce seminar and meetings pages to m… --- ## [Epinowcast 0.2.1 proposed roadmap](https://community.epinowcast.org/t/epinowcast-0-2-1-proposed-roadmap/131)

I have some unexpected time spare to do some epinowcast development. I’ve got a proposed roadmap here which I would appreciate some thoughts on (a few of the issues need decisions to be made before code can be implemente… --- ## [Handling delayed entry of symptom onset dates in line lists](https://community.epinowcast.org/t/handling-delayed-entry-of-symptom-onset-dates-in-line-lists/99)

@FelixGuenther drew our attention to a potential idiosyncrasy of line list data that he came across during his nowcasting work: it may be the case that the reference date (e.g. symptom onset date) is entered “retrospecti… --- ## [0.3.0 Roadmap (scheduled release date: 2023-03-01)](https://community.epinowcast.org/t/0-3-0-roadmap-scheduled-release-date-2023-03-01/111)

Hi all, As suggested in 0.2.0 package pre-release this is a post to discuss our roadmap for the next release (0.3.0). We need to think about which features we want and over what timescale we aim to put this release out. … --- ## [Assessing how much nowcasts are informed by observations](https://community.epinowcast.org/t/assessing-how-much-nowcasts-are-informed-by-observations/100)

When plotting our nowcasts, we probably want to distinguish between estimates based on complete data (everything beyond the maximum delay), estimates based on partial data (the actual nowcast), and (once we have forecast… --- ## [Epinowcast fediverse](https://community.epinowcast.org/t/epinowcast-fediverse/97)

I’ve been transitioning to mastodon and exploring hosting an instance. It seemed like the epinowcast platform could be a good home for this instance? The key pause has been having to commit to moderation which I strongl… --- ## [Optional profiling in cmdstanr](https://community.epinowcast.org/t/optional-profiling-in-cmdstanr/98)

This is just a heads up to all the stan-coders / advanced users here. I have created a “standalone” version of the code we use for making profiling in the epinowcast stan model optional. Basically just a conventient wra… --- ## [Handling downward corrections](https://community.epinowcast.org/t/handling-downward-corrections/63)

We have one case study (SARI hospitalizations in Germany) where it seems like there are periods when data get systematically corrected downwards rather than upwards as we usually see. So somehow some hospitalizations get… --- ## [Handling negative delays between reference and report](https://community.epinowcast.org/t/handling-negative-delays-between-reference-and-report/37)
