It was the best of tails, it was the worst of tails: The T-Copula – bggj
The Gaussian copula’s inability to model tail dependence can be a serious limitation in practice. This post introduces the t-copula, which shares many convenient properties with the Gaussian copula wh...

Just a heads up: If you're not using version control, never ever ever write "output-dir: ." or similar in your _quarto.yml file. It will delete everything in the base folder recursively (since it wants to refresh the output with this new setting). Luckily, I was using version control.

Just a little more than a month until parliamentary elections here in Iceland. I maintain an easily updated Quarto data-website in Icelandic. metill.is The repo is here: github.com/metill-is/me... Main takeaways: #quarto + EJS to automatically update front page with new content. #rstats

The second post in my series on copulas in Stan is up. In this one I define the Gaussian copula, show how to use it in Stan with a small example, then list some of its positives and negatives. bggj.is/posts/gaussi...

A Gentle Introduction: The Gaussian Copula – bggj
This post continues the series on copulas in Stan by introducing the Gaussian copula, discussing its properties, applications, and providing examples of how to implement it in Stan.

I'm looking for a post-doc and doctoral student to join my group at Aalto to work on Bayesian workflow, cross-validation, model checking, projection predictive model selection, inference diagnostics, priors, and survival analysis (I have plenty of research ideas, pick any combination) #Bayesian

I was so inspired after my first RSS Conference two weeks ago that I hurried up and became a fellow when I came back home to Iceland this week! Happy to join this large community of amazing statisticians!

After a great #StanCon2024, I've started a blog series on using copulas in Stan. This first post gives a quick introduction to what copulas are. I'll keep each post short but over time I hope to put together a repository of helpful content! bggj.is/posts/stan-c... #stats

Have you ever found #rstats rowwise computations cumbersome, slow, or memory greedy? If so, do give a try to **lay** -- a small 📦 from @romainfrancois.bsky.social and myself. Check courtiol.github.io/lay/ for examples, alternatives and benchmarks. You can use **lay** alone, or with **dplyr** 👀👇
