      You are probably familiar with the "Rule of 72" in investing: if an investment compounds at annual interest rate i, then the number of years for money to double is approximately 72 / i. For example, if an investmen...

It looks like a major update to {ggplot2} is coming (version 4.0.0), where Posit is switching the internals from S3 to S7. This will break many reverse dependencies of {ggplot2} (a reverse dependency is a package that depends on {ggplot2})...

A flexible hybrid approach to probabilistic stock forecasting that combines statistical model with ARCH effects, offering an alternative to traditional ARMA-GARCH models

We’re pleased to announce a new collaboration between the Bioconductor Training Committee and Physalia Courses, aimed at expanding access to high-quality training in bioinformatics and computational biology. This partnership builds on share...

As is often the case, it’s pretty easy to talk about “good” R packages. We can even wave our hands and talk about packages following “software standards” or “best practices”. But what does that mean? Most of us would agree that packages lik...

The kendallknight package introduces an efficient implementation of Kendall’s correlation coefficient computation, significantly improving the processing time for large datasets without sacrificing accuracy. The kendallknight package, following K...

With 20,000 observations, this reduces the required operations from 400 million pairwise comparisons to 200,000 operations.

Silver, Nasdaq Blockchain Economy Index, Bitcoin, and iShares Semiconductor ETF are always thought of as correlated with each other by investors. We will test this perception with the corrr package. The common perception appears to be correct based on the correlation analysis, specifically between the Nasdaq Blockchain Economy index and ...

A recent seminar introduced me to a new kind of statistical inference called post-Bayesianism. It has its own website, seminar series, Youtube videos and, most importantly, a cool name1. Will it catch on? I don’t know, but I think it’s interesting, and...

Remember our journey so far? We started with simple Markov chains showing how statistical word prediction works, then dove into the core concepts of word embeddings, self-attention, and next word prediction. Now, it’s time for the grand finale: if you want to build your own working transformer language model ...

I’m happy to share that my latest research paper, “Semi-Markov modeling for disease incidence risk and duration” has been accepted for publication in the journal Biostatistics & Epidemiology (Soetewey et al., 2025). Read the full paper here. T...
