This is just a simple post about the tooling for a small project I just wrapped up. For this project, I conducted a Bayesian data analysis and published the analysis to GitHub as a static website. The data analysis portion relied heavily upon the &lsqu...

In this post, we will once again return to the concept of convergent validity, and examine data from two fitness trackers to determine the extent to which their measurements agree. We will also examine the impact of the position of the tracker on the wrist, and see whether this makes ...

Way back in August 2020, I launched Big Book of R, a collection of free (and some paid) R programming books organised by categories like Geospatial, Statistics, Packages and many more. What started off as a 100 book collection has now grown to over 200 :D! Anyway, I felt was … The post Big ...

Aki Vehtari, Andrew Gelman, Dan Simpson, Bob Carpenter, and Paul-Christian Bürkner have just published a Bayesian Analysis paper about using an improved R factor for MCMC convergence assessment. From the early days of MCMC, convergence assessment has been a recurring (and recurrent!) question in the community. First leading to ...
