I don't think there can be any consciousness without time. #randomshowerthoughts
Some of the creators of Claude or other LLMs assign a greater than 0% chance the LLM is conscious. Something as high as 20 to 80%. This would be ethically problematic but I don't think this is right. Claude is non-committal on the topic but it also says it doesn't experience the passage of time.
“A simple comparison of means, with credible random assignment, beats a complex structural model with doubtful exclusion restrictions” - favourite quote so far
Great read tho! Very nice overview
X can cause Y without correlation, but the article only describes 3 ways this can happen. There are more! Eg Y may be multidetermined so X (and W, and Z) causes Y but the correlation isn’t detectable in the presence of other causes (or spontaneous Y occurrences)
Causes can exist without correlation, but they are hard to detect without a true experiment
“Every student learns that correlation does not imply causation. Few learn the converse: absence of correlation does not imply absence of causation. Both mistakes are common in applied work, and understanding why reveals something fundamental about what causal inference requires.”
Mental health interventions are now digital but over 50% of the variance in effectiveness for stress is due to differences in design and features. Expert design is needed and throwing everything at the wall is not helpful: www.jmir.org/2025/1/e71253/

Do you have concrete examples of the added value of #Rstats in the public or private sectors?
Include the most important factors (risk, lock-in, security, innovation...) to assess the added value.
Thanks!
I’m in this tweet and I don’t like it

Are young Gen Z men today becoming both more disengaged (not in education, employment or training) and more likely to desire children? How would we square that circle?
tagging @rkwilkins.bsky.social because #HILDA is a great resource for fertility researchers but I don't know where to find them!
Is there something in the water of young men today?
facebook was listening... facebook is always listening
Would you like to look into Medicare claims for mental health support over COVID - I think subsidies were extended for extra psych visits but can’t find records or dates. Other subsidies or State-specific programs might have been provided as well. Could provide nice evidence for treatment efficacy
Rising trend in psychological distress among school-aged youth peaked in 2022, replotted from latest results of Mission Australia Youth Survey (2012-2025)
Latest data from Australia indicates mental ill-health among 15-19 year olds has already peaked. But what caused it to peak? And what caused it to turn around?
Indeed. It seems with sensible immigration policies (skill/education based perhaps) we could trust the market to distribute the population where it will be most productive and avoid most of the ill-effects of rapid decline
Does anyone else just surf LinkedIn hoping to find a job using R, Quarto, or Shiny? #rstats
That seems smart
That makes more sense than the ANCOVA to me. But my thinking is you want the effect of time because that is the only variable in the implicit DAG which is producing the change.
Devils advocate if there is no treatment group ANCOVA is the wrong choice. It answers if pre predicts post. You want if measure changes over time. Second model does that.
That's a tough decision to go through, but getting a PhD can sometimes be an albatross around your neck. It can be hard to know what the good and bad choices are while you are making them - bad luck now can look like a good choice in a few years time and we are all navigating by the rear view mirror
America is great when kids can't play soccer because the secret police may steal their parents
That’s what drove me to always declare the method!

Major depressive episodes among US teenagers peaked in 2021 and have been declining since. More evidence challenging simplistic theories of teen mental health
I did not plan to read all 240 posts on observational evidence today. I did not WANT to read all 240 posts on observational evidence today. What did you do today? Sigh…
The trouble with being an #rstats celebrity is that everything you post about statistics will be taken veeeery seriously :-P
