We've got two online IPD meta-analysis training courses this Autumn, with places still available - one is a general introduction about doing IPDMA projects (the whole process, not just the stats bit) & the other is about the statistical modelling aspects - more here: www.ipdma.co.uk/training-cou...

For those who haven’t seen, a little something me and @stevecolewriter.bsky.social have been busy on…

This weekend, we at Radio Free Skaro celebrate our 20th anniversary episode with a bumper edition of #FluidLinks! Send in your questions and comments about Doctor Who, about its future, or even about Radio Free Skaro. Thanks for all your support over the past two decades!

Looking forward to this release in January …. we’ve still got new Who in 2027 thanks to @0tralala.bsky.social

About once a month, for the last few years, I've been asked for a sample size in a prediction study and have been able to either point to pmsampsize or just run a quick sim myself. This package is such a blessed contribution to #rstats and #statsky @joieensor.bsky.social @richarddriley.bsky.social

pmsampsize: Sample Size for Development of a Prediction Model

Computes the minimum sample size required for the development of a new multivariable prediction model using the criteria proposed by Riley et al. (2018) &lt;<a href="https://doi.org/10.1002%2Fsim.7992...

Right. Okay. This requires some backstory. In 1984, a small, low budget film studio in North Carolina produced a parody of Star Wars, called Hyperspace. It was released in the U.K. as ‘Gremloids’. The main character, shown here, was Lord Buckethead.

As it's schism month, I think you should also explain the Binface / Buckethead schism

Our book “Individual Participant Data Meta-Analysis: A Handbook for Healthcare Research” was released five years ago this month! Thanks so much for all the feedback - lovely hearing how much it has helped researchers on their IPDMA journey. That’s exactly why we wrote it! 5 years already … how?!
