Inspired by @nrennie.bsky.social excellent #TidyTuesday plot on the power of passports, I adapted the idea to look at refugee origins.

This chart ranks countries of origin of refugees, asylum-seekers, and others in need of international protection, grouped by region.

#RStats #ggplot2 #Refugees
Bump chart faceted by world regions showing the top countries of origin of refugees, asylum-seekers, and others in need of international protection. Asia and Africa rank consistently high, driven by long-term crises such as Afghanistan and Sudan. The Americas and Europe also appear high due to more recent crises in Venezuela and Ukraine.

So excited for this! As well as ‘C for R users’ I’ll be talking about contributing to base R more generally, and doing a live demo of the R Dev Container. #RStats

If one wanted to hire a professional #rstats #rshiny developer to work work with qualitative/text data in particular (so many involve a dashboard for search/semantic/sentiment analyses), do you have any recommendations of individuals or companies? (please repost)

🚨 The "penguins" data is coming to the base #rstats{datasets} in 4.5.0!

@ellakaye.co.uk & @HeathrTurnr.fosstodon.org.ap.brid.gy r prepared an adapted and a raw version of the data set based on the {palmerpenguins} 📦 by @allisonhorst.bsky.social @apreshill.com and Kristen Gorman.

📈 Scatter plot:
Scatter plot of bill depth vs. length by species (color) and sex (symbol). It shows positive correlations for all species with males tending to have bigger bills than females. sym <- c(1, 16) pal <- c("darkorange","purple","cyan4") plot(bill_dep ~ bill_len, data = penguins, pch = sym[sex], col = pal[species])

- Handles remote packages with remote deps much better!
- IDEs are now handled more consistently and are better documented
(there's a new vignette "Using an IDE with Nix shells)
- Many bugfixes and overall improvements!

If you know simulation based calibration checking (SBC), you will enjoy our new paper "Posterior SBC: Simulation-Based Calibration Checking Conditional on Data" with Teemu Säilynoja, @marvinschmitt.com and @paulbuerkner.com
arxiv.org/abs/2502.03279 1/7
Title: Posterior SBC: Simulation-Based Calibration Checking Conditional on Data Authors: Teemu Säilynoja, Marvin Schmitt, Paul Bürkner, Aki Vehtari Abstract: Simulation-based calibration checking (SBC) refers to the validation of an inference algorithm and model implementation through repeated inference on data simulated from a generative model. In the original and commonly used approach, the generative model uses parameters drawn from the prior, and thus the approach is testing whether the inference works for simulated data generated with parameter values plausible under that prior. This approach is natural and desirable when we want to test whether the inference works for a wide range of datasets we might observe. However, after observing data, we are interested in answering whether the inference works conditional on that particular data. In this paper, we propose posterior SBC and demonstrate how it can be used to validate the inference conditionally on observed data. We illustrate the utility of posterior SBC in three case studies: (1) A simple multilevel model; (2) a model that is governed by differential equations; and (3) a joint integrative neuroscience model which is approximated via amortized Bayesian inference with neural networks.
