Predict housing prices in Austin TX with tidymodels and xgboost
This is the latest in my series of
screencasts demonstrating how to use the
tidymodels packages, from just getting started to tuning more complex models. My screencasts lately have focused on xgboost as I have participated in
SLICED, a competitive d...
Could there be incentives to cycle through a red light?
This is of course a rhetorical question! Because cyclists must stop when the light is red! … But … there is always that moment, on a bicycle, when you stop, and then you say to yourself the worst part is that the lights are badly regulated, and I know that the next ...

Fragment: Tools of Production – ggalt and encircling scatterplot points in R and Python
In passing, I note ggalt, an R package containing some handy off-the-shelf geoms for use with ggplot2. Using geom_encircle() you can trivially encircle a set of points which could be really handing when demonstrating / highlighting grouping various sets of points in a scatterplot: See the end of this post ...

census 2020: some quick visuals of demographic change
Intro
A quick/simple post: using the PL94171 package to access Census 2020 counts. Census data won’t be API-accessible until ~late September; these data are available, however, for redistricting purposes – albeit in a funky format. The PL94171 package can be used to download and re-structure these files for super convenient ...
