New paper "Cross-validatory model selection for Bayesian autoregressions with exogenous regressors" with Alex Cooper, @dan_p_simpson, Lauren Kennedy, and Catherine Forbes

One FAQ is "Can you use LOO or cross-validation in general for time series?" The short answer is "Yes", and I've had a longer answer in CV-FAQ https://avehtari.github.io/modelselection/CV-FAQ.html#9_Can_cross-validation_be_used_for_time_series

Now we have a better answer on what kind of cross-validation is good with timeseries!

@NicoleCRust field-specific hashtags for paper announcements and threads might not work so well for those of us with poor memories and interests across multiple fields, because we would have to remember the specific hashtags for each field.

The Mastodon advanced web interface allows you to follow combinations of hashtags (instructions here: https://blog.djnavarro.net/posts/2022-11-03_what-i-know-about-mastodon/#tracking-hashtags) but it doesn't appear to allow for (#neuroscience AND (#NewPaper OR #PaperThread)), plus I think I found a bug.

For now, I think I will follow (#PaperThread OR #NewPaper OR #NeuroPaperThread OR #NeuroNewPaper OR ...).

Plus, I'm copying in @cogsci #CogSci and #CompCogSci because this is an issue that needs to be discussed in all research communities.

Hi #science #research #mastodon community! A few days ago, a post of mine recieved a lot of attention. Thanks for the engagement and the very interesting suggestions! https://neuromatch.social/@LeonDLotter/109632615134117119

On #Twitter, I loved the common practice of writing threads explaining new #preprints and #papers in an understandable way.
I uttered my concern that through the chronological timeline here people might miss interesting science. A solution would be to agree on names for hashtags and/or a.gup.pe groups to ease tracking these "paper threads".

Following tags were named more then once: #newPaper #paperThread #preprint #researchPaper #mastoPrint #tootPrint.
Also, there was #tootorial, but that might be a slightly different category?

I heard people like participation - so let's do a poll! What's your favourite tag for threads explaining research articles? 📊​ Multiple choices possible!

How often should you clean your room?

This is the title of this #CombinatorialOptimization #paper. The take on the question is truly original.

Authors went at length to investigate the issue and prove a logarithmic upper bound.
