TBF that bit is ok. A certain form of MMRM is equivalent to a certain MI, without the Monte Carlo error of MI. Calling MI (without any further info) a sensitivity analysis for this is wrong.

I assume lots of you are also receiving this. Somehow the entire message comes off as dripping with contempt.
Hooold!

Stumbled across this podcast on clinical trials today and enjoyed it. I like skilled interviews talking to experts and this is that. cc @andygarrett.bsky.social @timpmorris.bsky.social

My mother-in-law just sent “This rain 🌧️🤨” to the family whatsapp and within 60s almost everyone had replied with the current rain status in their locality. Take THAT everyone who says the weather isn’t a banger of a conversation starter.

Preprint!📢

We examined reporting- and open science practices in simulation studies in psychology with a questionnaire

Importantly, we asked ‘why?’

Why were results omitted? Why weren’t MCSEs reported?

Also: how do researchers evaluate simulation studies in their field?

I was chatting to a friend about AI, academia, fraud, authenticity and creativity and for some reason it led me down a rabbit hole to the classic satirical TV news show, The Day Today; and the great bluffer of the reporting world, Peter O'Hanraha-hanrahan.

Bear with me on this one...

As a former academic PI still carries a certain weight for me so it’s gotta be UK Private Investigators

Suggestions for my possible affiliation. It’s selected ‘LETS Go UK, Portsmouth, United Kingdom’, but then offered some others:
‘We found potential matches. Please review the suggestions below:

Wonderful bit of ‘added value’ here. New manuscript system seems to use ‘AI’ to suggest my primary affiliation for an accepted paper. That the paper is accepted means I already told the system my affiliation. What a superb list 😆

What’s your personal protocol when you receive an “as per my earlier email” but the thing was not in fact in the earlier email?

I've done an analysis where the outcome unit was in hours, and in the results we report decimal hours (e.g. 0.89 hours) rather than in HH:MM. A respected colleague thinks we should use the later. Who is more correct? True pedants only please.

*ahem* @timpmorris.bsky.social

You just know people will interpret 0.89 hours as 1h29m. So I’d go defensive and use HH:MM

Worth remembering when looking at the horrific scenes in the US right now that both Reform and the Tories have pledged to bring in ICE-style organisations to the UK if they win power
