📚 I have a few misprinted (black and white) hardcovers of Geocomputation with R. Happy to send them to readers in Europe. Email me if you’d like one — if there’s lots of interest, I’ll draw randomly. Shipping costs optional. #Gischat #Giveaway #RStats #RSpatial #geocompr

Researchers value null results, but struggle to publish them “If it had been widely disseminated in my field,” they lamented, “it would have saved me 2+ critical research years!” www.nature.com/articles/d41...

Survey finds that fear of reputational harm and a lack of support and publication platforms are among respondents’ key concerns.

Announcing sparse data support in tidymodels! #RStats users, get faster model fitting, less memory use, & efficient handling of big datasets with zeros. Check out blog: www.tidyverse.org/blog/2025/03... @emilhvitfeldt.bsky.social's SLC UseR talk: www.youtube.com/watch?v=l1zv...
A hexagonal logo on the left with a dark purple background and colorful, wavy lines across it reads "tidymodels". To the right, a white box with rounded corners displays the text "c(0, 0, 1, 0, 3, 0, 0, 7, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 3, 0, 0, 7, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0)". The background is teal with a subtle dotted pattern. A small "posit" logo is in the top right corner.

Por una lesión vuelvo a un vehiculo con grua para subir una silla de ruedas. Por lo que barajo la ID.buzz como vehículo único (pero para moverse por Alicante uffff), eBerlingo+eléctrico(400km); o una Híbrida enchufable. Ahora tengo Tesla MYP 2022 @luisvaldes.bsky.social ¿qué me recomendáis?

Yes, the interoperability between Julia and many other languages is amazing! I often work in the other direction, calling for example these from within Julia code: - R (github.com/JuliaInterop...) - Python (github.com/JuliaPy/PyCa...) - Matlab (github.com/JuliaInterop...) from Julia. #julialang

A book I've grown to like very much is Regression and Other Stories by @statmodeling.bsky.social, Hill and @avehtari.bsky.social. I've never read it cover to cover. Instead, I occasionally grab it and open a random page. Almost always there's a nugget of wisdom.

The image is a cartoon depicting a conversation between two people sitting across from each other at a desk. The person on the left asks: 

"Are you concerned about the rise of artificial intelligence?" 

The person on the right replies: 

"No, but I'm worried about the decline of real intelligence."

"It does not make sense to think of our judgements as being estimates of ‘true’ probabilities." David Spiegelhalter's excellent introduction to the nuances and intricacies of probability. doi.org/10.1038/d415... #Methodology #Statistics #Probability 🧪
There is a limited range of well-controlled, repeatable situations of such immense complexity that, even if they are essentially deterministic, fit the frequentist paradigm by having a probability distribution with predictable properties in the long run. These include standard randomizing devices, such as roulette wheels, shuffled cards, spun coins, thrown dice and lottery balls, as well as pseudo-random number generators, which rely on non-linear, chaotic algorithms to give numbers that pass tests of randomness. In the natural world, we can throw in the workings of large collections of gas molecules which, even if following Newtonian physics, obey the laws of statistical mechanics; and genetics, in which the huge complexity of chromosomal selection and recombination gives rise to stable rates of inheritance. It might be reasonable in these limited circumstances to assume a pseudo-objective probability — ‘the’ probability, rather than ‘a’ (subjective) probability. In every other situation in which probabilities are used, however — from broad swathes of science to sports, economics, weather, climate, risk analysis, catastrophe models and so on — it does not make sense to think of our judgements as being estimates of ‘true’ probabilities. These are just situations in which we can attempt to express our personal or collective uncertainty in terms of probabilities, on the basis of our knowledge and judgement.
