There is an ancient saying. Okay, well, now that I think about it maybe it’s not so ancient: it’s only been around since 2017 or thereabouts. And actually it’s more of kind of friendly warning than it is a saying. And really it’s only used by a weird group…

Mapping runkeeper data

Published: January 4, 2026 13:00

One of my constant irritations, as someone who loves to run and loves to analyze data, is that despite the many wonderful apps and gadgets we have for taking detailed measurements of our exercise patterns, the analyses that get shown to us as end-users of…

Two githubs, one laptop

https://blog.djnavarro.net/posts/2025-12-08_two-github-one-laptop/

Published: December 7, 2025 13:00

I have for some time been plagued by an annoyance in the git configuration on my various computers: I am but one woman, but I have multiple github accounts. There are reasons for this, of course. For the purposes of my personal projects and my open source…

Some notes on survey weights

🫀 : Okay. So. Um. Hey babe. You know that GAMLSS regression post we wrote? 🧠 : Do you mean the monstrosity that took an entire month out of our lives, spawned an unhinged prequel post about the Box-Cox power exponential distribution and then another…

Some notes on probability judgement

There is a statistic that is currently going viral on bluesky. It is not the first time this statistic has gone viral. It has happened several times before, and every time it happens I get really angry because the statistic is false. The claim is this:…

Linear cosine palettes

Published: September 13, 2025 14:00

So. Looking back at my history on this blog I have noticed that I, ummmmmm, tend to write long posts. It is a character flaw of which I am acutely aware. When I want to understand a thing I feel a kind of psychological compulsion to delve too deeply into…

GAMLSS, NHANES, and my own personal hell

https://blog.djnavarro.net/posts/2025-09-07_gamlss/

Published: September 6, 2025 14:00

Okay, so two posts ago I was whining about the Box-Cox power exponential distribution, and promising that it would be followed by a new post whining about the generalised additive model for location, shape and scale (GAMLSS). It turns out I was lying…

Splines, B-splines, P-splines, and a disapproving kitten

https://blog.djnavarro.net/posts/2025-09-06_p-splines/

Published: September 5, 2025 14:00

library(dplyr) library(purrr) library(tibble) library(ggplot2) This is a post about splines. It’s also a post about “basis splines” and “penalised splines”, a fact that does not endear it to me greatly. Indeed, let’s be brutally honest here, dear reader:…

The Box-Cox power exponential distribution

https://blog.djnavarro.net/posts/2025-08-02_box-cox-power-exponential/

Published: August 1, 2025 14:00

I have for the longest time been intending to write up some notes about generalised additive model for location scale and shape (GAMLSS) regression and its application to modelling growth curves of various kinds. It’s a problem that pops up in my…

Generating quarto syntax within R

library(dplyr) library(purrr) library(ggplot2) library(quartose) library(babynames) It is Saturday morning in my quiet neighbourhood in Sydney’s inner west, and for no particular reason I’m thinking about the strange human convention of assigning names…
