Monday at 1pm BST we have @xmjandrews giving a session on prior and posterior predictive checks to ensure that our #bayesian models make realistic predictions eventbrite.co.uk/e/posteriorpri…

Today's session with @chaddlewick is now available on Youtube! A stellar introduction to loads of statistical concepts! youtu.be/Wvd6gEkVfJk

@sim_school Thanks :) it was a pleasure to take part in this great summer school!

Tomorrow we have @chaddlewick presenting a session on simulating response accuracy data using logistic multi-level models - this will be particularly excellent for people in the psychometrics field! Kicks off at 13:00BST!

@sim_school @OleMiss couldn't make the live session, so great it's on youtube! thanks!

Today's excellent introduction to Simulation of Regression using R with Andrew Hales of @OleMiss has been uploaded here: youtu.be/x2hhc5KYw-c

This starts in <1hr and tickets are still available. The link will be sent out again at about 15:50BST!

@LindaKKaye This is 'moustache park' right?

Hello! This is the Twitter profile for the 2021 Simulation Summer School which was organised by @psypag and @bpsmscp. This first session was delivered by @LisaDeBruine who introduced the excellent Faux package in R. youtube.com/watch?v=O8YRgc…

📢 We have been at it again: together with our friends at @questbih we have been planning the 4th Oxford | Berlin Summer School --- and this promises to be the best one yet! 🗓️ 20--23 Sept 2021 🎙️ online or hybrid format 🇬🇧🇩🇪 🎟️ free to attend Details 👉 #2021-05-01_oxford-berlin-summer-school2021" target="_blank" rel="nofollow noopener">ox.ukrn.org/events/#2021-0…

Come and do a PhD with us 😀. One fully-funded teaching scholarship (UK fees and stipend) for an Oct 2021 start in any area of psychology.

@maltoesermalte ahh okay, I guess that complicates things a little. Maybe a multivariate model then instead!

@maltoesermalte no problem! Although if P(subtask_b = 1) is conditional on the outcome of subtask_a, then this model wouldn't be totally appropriate - they wouldn't be two independent trials :| if one subtask is just easier/harder (unconditionally) I would consider an indicator for subtask type

@maltoesermalte Maybe Glmer(subtask_accuracy ~ condition + (1|id) + (1|trail) + (1|subtask)) as logit or probit model
