Last fall, my co-authors Stephanie Zimmer, Rebecca Powell, and I released Exploring Complex Survey Data Analysis Using R. Earlier this August, we had the joy of teaching a workshop based on the book at useR! 2025. One of our favorite examples in...

Another interesting decision, now for 'Beyond Nelson-Siegel and splines: A model-agnostic Machine Learning framework for discount curve calibration, interpolation and extrapolation'

Getting back Into It It’s been a while for this website; a lot of my work has been used on projects that can’t be easily shared here. That said, I have been at the Edinburgh Fringe this month supporting my wife, and I wanted to use a Tidy ...

Cloud providers are no longer just offering traditional x86-based servers, ARM-based servers are now becoming a serious alternative. And for good reason: they’re often far more cost-effective and power-efficient than their x86 counterparts. For ...

1 Introduction Data preprocessing is a cornerstone of any data analysis or machine learning pipeline. Raw data rarely comes in a form ready for direct analysis — it often requires cleaning, transformation, normalization, and careful handl...

Motivation Epidemiological delays inform about the time between two well-defined events related to a disease. The serial interval (SI) of an infectious disease is defined as the time between symptom onset in a primary case (infector) and symptom onset in a secondary case (infectee).

1 Introduction Missing data is one of the most common challenges in data analysis and statistical modeling. Whether the data originates from surveys, administrative registers, or clinical trials, it is almost inevitable that some values are abs...

Bernstein has conducted an analysis of the U.S. supply and demand balance in analog and discrete semiconductors, particularly in light of the potential introduction of Section 232 tariffs. The analysis focuses on the implications for major companies, including Texas Instruments, Analog Devices, Infineon Technologies and Renesas. According to analysts led ...

Wikipedia donations style note: Because of delays with my scholarship payment, if this post is useful to you I kindly ask a minimal donation on Buy Me a Coffee. It shall be used to continue my Open Source efforts. The full explanation is here: A ...

Connecting the VSCode debugger to cpp11 code.

Back in 2018, there was a survey on Gallup, about honesty and ethical standards, per profession More than four in five Americans (84%) again rate the honesty and ethical standards of nurses as “very high” or “high,” earning them the top spot among a diverse list of professions for the 17th consecutive ...

Instead of flashcards, we Rube Goldberg’d this with Bioconductor! Analyzed 3,280 E. coli genomes from NCBI, detecting ESBL genes in 84.4% of samples. CTX-M-15 was most common. Helped us understand gene nomenclature and sequence analysis! 📊🔬 Motivation I’ve always had a hard time learning and remembering all these genes for antimicrobial ...

Introduction When teaching, for my practicals/tutorials and for about half of my lectures I find myself preparing them using R Markdown and laterly Quarto. I enjoy preparing the material in R Markdown and Quarto because it gives me a reproducible way o...

Below are the slides for my Futureverse P2P: Peer-to-Peer Parallelization in R talk that I presented at the useR! 2025 conference at Duke University, Durham, North Carolina, United States. Title: Futureverse P2P: Peer-to-Peer Parallelization i...
