This post presents a function `mlReserve()` for machine-learning loss reserving on 'real-world' triangles, based on a fork of the 'ChainLadder' package. It includes two experiments, each scored against a known true reserve: (A) Two triangles from an individual-claims simulator (Wang & Wüthrich), embedded below: chain ladder vs mlReserve, in detail; (...

Pipeline setup {pipeflow} builds a pipeline by adding one R function per step with pip_add (see also the Get started article). In this post, we’ll work with the following toy pipeline: step load produces a sequence step clean doubles it step fit sums it, and step report formats ...

The North American Bioconductor Conference 2026 (([BioC2026])(https://bioc2026.bioconductor.org/)) took place from August 10-12, 2026, at the Fred Hutchinson Cancer Center in Seattle, Washington. The conference brought together researchers, dev...

Three hundred twenty-nine new packages were submitted to CRAN in July. Here are my Top 40 picks in nineteen categories: Agriculture, Artificial Intelligence, Climate Studies, Computational Methods, Ecology, Epidemiology, Genomics, Machine Learni...

In 2019 I wrote a post with seven reasons policy professionals should learn to code. Now that AI can write reasonable code, I’ve had a number of people ask me if it’s still worth learning to program. Based on the evidence I’ve seen, AI appears to be a ...

I had a lot of fun this morning, brainstorming and assembling this _Analytics Pipeline_ for Dashboards with Claude (and yes it takes much, much more than only 10 prompts).

There are ten public training courses left in 2026, running through October and November. If you’ve been meaning to learn Python, build your first Shiny app, or get to grips with machine learning in R, there’s still time to do it befo...

Executive Summary MicroStrategy (MSTR) has fundamentally transitioned from a traditional enterprise software firm into an equity-based Bitcoin (BTC) holding vehicle and treasury operation. Evaluating MSTR using conventional corporate finance metrics (such as Price-to-Earnings or EBITDA multiples) fails to capture the core driver of its equity valuation: the dynamic Net Asset ...

You can read the original post in its original format on Rtask website by ThinkR here: We chose React to learn it. The AI wrote it for us. Diary of a rewrite, episode 1 of 4. In February 2026 we chose React to rebuild an internal tool, knowing full well it would take ...

The last post identified potential transition pathways for truck drivers based on how closely other occupations matched them on skills, abilities and knowledge. This post follows the same basic approach across a wider range of occupations and asks whether two proxies could stand in for the ratings where no O*...
