Scientific datasets are riddled with copy-paste errors Initial results from scanning through Excel files belonging to 600 published scientific papers.

Markus Englund built a tool for identifying repetitive sequences in scientific datasets! Read up here: www.sciencedetective.org/scientific-d...

Learning R for Good Research Practices: Part 1 | Alexander Gibson In this multi-part blog series I outline some steps to help start learning R. Part 1 is a background on R, packages and resources and tips on how to get started learning.

New Blog: Learning R for Good Research Practices‼️

Read Part 1: alexdgibson.com/blog/r_1/

This is the first of a multipart series where I go into my experiences learning R, highlighting tips and resources that were essential in my learning.

We need more people reading more books! Such an important skill and has done so much for me.

There’s nothing better than a good book, a change in perspective, beliefs or the generation of new ideas.

Last week, #AusHSI PhD student @alexdgibson.bsky.social presented at #AIMOS2025, highlighting a new global issue of unreliable data within #clinicalprediction model research and clinical practice, which has potential to influence patient outcomes and evidence-based decisions. @aimosinc.bsky.social

Genuinely enjoying how much layered wrongness is here.

A kind of beautiful tiered wedding cake of misconceptions.

Just BATHE in the warm rolling folds of daftness.

First up: Alexander Gibson @alexdgibson.bsky.social: Poor Data Provenance in Published Clinical Prediction Model Research.
I was seriously concerned about some of the Kaggle Datasets - those on stroke and diabetes raised concerns about data being fake.

Ok, time for a short thread about this paper.

My sense over the past six months or so is that chain-of-thought prompting as used in e.g. ChatGPT o.3 improves substantially upon previous systems such as ChatGPT 4.o, at least for certain tasks.

But how revolutionary is it?

Reading over my brother’s undergraduate assignment.

Criteria has a section: β€œIs there an appropriate amount of detail in this section so that you could replicate this study?”

I don’t remember learning about replication in my undergrad! Nice to see it getting some air time.

And if I do need to learn something new I just go to the documentation of the function/package. I trust the devs more than an LLM at this point in time.

I feel the time taken to specifically explain what I want the output code to be from an LLM to be, could be spent just writing the code. Maybe I’m not great at prompting?

16.05.2025 05:40 β€” πŸ‘ 2    πŸ” 0    πŸ’¬ 2    πŸ“Œ 0

I’ve basically never use them. Every time I have tried to use LLMs for coding it hasn’t output what I’m after. Nearly always have to make major changes that anecdotally take longer than if I were to write the code from scratch.
