I try and give an overview of this very confusing concept: davidhodgson.me/post/sm3_cop1/ I think it's good ID modellers try and get a solid understanding of this as it's going become increasingly important for vaccine development over the next few years. https://davidhodgson.me/post/sm3_cop1/05 Oct 2025 19:25 +0000at://did:plc:msg4mtsu4yimwddxhmxsaqzl/app.bsky.feed.post/3m2hta33moc2ohttps://bsky.app/profile/dchodge.bsky.social/post/3m22jzaqiy22h🚀 New tool: Reversible Jump MCMC running in your browser! Built an interactive widget for fitting mixture distributions when you don't know how many components you need.

You’re not alone When I first saw spreadsheets full of columns labelled ELISA_OD, PRNT50, HI_titre, and PVNT_ID50, I had no idea what they really meant.

PCR? Symptoms? Antibodies? Being able to pass it on? I’ve written a blog digging into why infection isn’t a simple on/off switch, and why the definition you choose matters for modelling, vaccines, & public health. https://davidhodgson.me/post/sm1_what_is_inf/17 Sep 2025 08:37 +0000at://did:plc:msg4mtsu4yimwddxhmxsaqzl/app.bsky.feed.post/3lyzgmqvi6c26https://bsky.app/profile/dchodge.bsky.social/post/3lyv2ahwf7c2r🚨 New vignette: reversible-jump MCMC for epidemic change-points Used RJMCMC to infer piecewise attack rates in an SEIR model — the sampler figures out how many change-points there are and where they happen.
