Calculating pi from coin flips (without randomness) YouTube video by Stand-up Maths

This video is *bananas*—you can estimate π from a ton of random coin flips bc the expected prop of heads/total after 50%+ of the flips are heads = π/4

Here's an #rstats version I made of Matt's Python code in the video gist.github.com/andrewheiss/...

With 10 million random flips I got 3.131381

Yay! Made me look forward.

Interactive resources With the power of OJS and Quarto, I’ve created a few interactive websites to illustrate trickier statistical concepts when teaching. Check them out (and adapt and copy as much as you want!) With links to three different websites (accessible at the main link in the post)

Finally got around to adding fancy links to my different interactive teaching websites for showing things like p-hacking, p-value interpretations, and (still-in-draft-form) DAGs at www.andrewheiss.com/teaching/ #rstats #QuartoPub #statsky

📣 IJPA Award Highlight
Congratulations to Mr. Nasir Uddin on receiving the #ASPA International Chapter Best Student Paper Award for his IJPA article “Impact of Crime and Insecurity on Citizen Trust in Public Institutions: Evidence from Bangladesh” (2025).

Various stuff happened during that time (that impacted both locations)?

The Spring 2026 course website for my grad causal inference class is up and running. Was inspired by @andrew.heiss.phd and @mattblackwell.bsky.social to move my materials over to a standalone site and use as little of Canvas as possible.

Finally got around to removing broom::tidy(), broom::glance(), and broom::augment() from my class examples in favor of parameters::model_parameters(), performance::model_performance() and marginaleffects::predictions() because they're *so nice* for teaching! #rstats #easystats

So cute!!!

This makes a good question for the bar exam.

I don't know how I've missed it because it's *right on the documentation home page*, but if you use {glue} for nice string interpolation in #rstats and you have {stringr} loaded (likely through the tidyverse), you can use str_glue() instead of glue::glue() or loading library(glue) glue.tidyverse.org

Do you teach #rstats? Do your students complain about how lame and old-fashioned dplyr is? Don't worry: I have the solution for you: github.com/hadley/genzp....

genzplyr is dplyr, but bussin fr fr no cap.

The {sf} package continues to blow my mind with how easy it is to make maps with #rstats and ggplot (code for that map here gist.github.com/andrewheiss/...)

We have progressed from data collection to data analysis.

We had a great time!

This morning my ChatGPT quota was inexplicably exhausted.

It took a while but I pieced it together. Voice mode somehow got activated when I went to bed.

The bot then engaged in a 10 hour conversation with my snoring dog, answering questions the pup wasn’t asking and praising him for his insight.

Happy birthday! And it's on the badge!

Woohoo! You went to Data Disneyland!

Scary. This is the CVS I use to get my prescriptions all the time and my daugher's school is just one mile from there.
