Introducing tidynorm

Here’s a brief introduction to the new {tidynorm} package.

In Remembrance

Weinreich, Labov, and Herzog (1968) is a foundational text in my subfield of linguistics. Entitled “Empirical foundations for a theory of language change,” it’s both a…

Random Effects and Overdispersion

Today in my stats class, my students saw me realize, in real-time, that you can include random intercepts in poisson models that you couldn’t in ordinary gaussian models, and…

Random effect priors, redo

For me, teaching stats this semester has turned into a journey of discovering what the distributional and ggdist packages can do for me. The way I make illustrative figures…

This might be a “everyone else already knew about this” thing, but I’ve finally gotten to a place of understanding about setting default colors scales for ggplot2, so I…

Building up a complex `{gt}` table.

Recently, for class notes on probability/the central limit theorem, I wanted to recreate the table of 2d6 values that I made here. A really cool thing I found between that…

Rolling for Damage with the Central Limit Theorem

I’ve been playing a lot of Baldur’s Gate 3 lately. My party has gotten to max level, and we’re running around, casting spells and taking names.

Troubleshooting RStudio for GitHub Classrom and Codespaces

A living document

I’m teaching a class on quantitative methods in linguistics, and after getting tired, over the years, of debugging everyone’s computer before we could get to the content of…

Experimenting with Object Oriented Programming in R

I’ve been doing a lot of python development recently, and really leaning into object oriented programming for my projects. For example, in the aligned-textgrid package, I…

Working with the Discrete Cosine Transform in R

I’ve been working a lot with the Discrete Cosine Transform in python, specifically as it’s implemented in scipy. But, I really prefer doing my data munging and stats in R.¹ W…

Some lessons in using Github Classroom and Codespaces

I’m currently teaching a computational linguistics course, and for just the second time, I’m using Github Classroom to manage assignments. I might make a few posts about…

Thinking About Hierarchical Variance Parameters

I’m still thinking about priors, distributions, and logistic regressions. The fact that a fairly broad normal distribution in logit space turns into a bimodal distribution…

Getting a sense of priors for logistic regression

This summer, I’ve been spending some time getting more familiar with the nitty-gritty of Bayesian models, and I’m working on some modelling in Stan for logistic regression.…

Changing Project Defaults

I’ve moved a bunch of R defaults that I want for each post from .Rprofile into _defaults.R, and now run source(here::here("_defaults.R")) in each post where I want them.…

Using Quarto Blogs for Teaching

This semester I was teaching two R intensive courses: Quantitative Investigations in the Social Sciences and Quantitative Methods in Linguistics. For both courses, I had…

Simulating DND Rolls

I’ve recently started playing Dungeons and Dragons, and have been really enjoying the campaign my sibling runs. I’m still getting a handle on the mechanics, especially in…

A handy dplyr function for linguistics

One of the new functions in dplyr v1.1.0 is dplyr::consecutive_id(), which strikes me as having a few good use cases for linguistic data. The one I’ll illustrate here is for…

Making a Plotly Plot
