We have just merged a new vignette ([Estimating the effective reproduction number in real-time for a single timeseries with reporting delays • epinowcast](https://package.epinowcast.org/dev/articles/single-timeseries-rt-estimation.html)) that discusses how to use `epinowcast` to estimate the effective reproduction number whilst adjusting for right truncation (i.e. nowcasting). This is an extension of some earlier work @sbfnk and I did last year ([Nowcasting in a real-time analysis pipeline to estimate the effective reproduction number with missing data and reporting delay](https://community.epinowcast.org/t/nowcasting-in-a-real-time-analysis-pipeline-to-estimate-the-effective-reproduction-number-with-missing-data-and-reporting-delay/43)) but uses the new functionality in `epinowcast` to do everything jointly. Opening this thread for any feedback and/or discussion that isn’t suited for an issue (at least not straight away).

This is also very related to a recent preprint from @adrianlison which includes the first (that I know of) model that can jointly estimate R\_t and correct for right truncation.

There are a fair few pain points and in many ways this vignette mostly serves to highlight where more work is needed.

There are already a few issues open to attack some of these which others are very welcome to get involved with:

- [Check that retrospective nowcasting works as expected · Issue #318 · epinowcast/epinowcast · GitHub](https://github.com/epinowcast/epinowcast/issues/318)
- [Add effective reproduction number vignette plots to package as functions · Issue #317 · epinowcast/epinowcast · GitHub](https://github.com/epinowcast/epinowcast/issues/317)
- [Porting distribution wrappers into their own package · Issue #316 · epinowcast/epinowcast · GitHub](https://github.com/epinowcast/epinowcast/issues/316)
- [Extract work on simulated double censoring into its own lightweight package · Issue #315 · epinowcast/epinowcast · GitHub](https://github.com/epinowcast/epinowcast/issues/315)
