Life satisfaction mostly declines with age. Previous findings (esp. the famous U-shaped age-SWB trajectory) were artifacts of misspecified models. doi.org/10.1093/esr/...

A new paper I worked on is out in Justice Quarterly! I won't speak on the substantive nature of the paper as I worked solely as the methodologist, but I developed a new matching method not otherwise described in the literature, and I want to tell you about it!

For the open source devotees out there, I've integrated @OpenFreeMapOrg into the #rstats {mapgl} package.

Do `maplibre(style = openfreemap_style("liberty"))` for an excellent street map with 3D buildings; "bright" & "positron" are also available.

Map with no API keys required!

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN.

It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package.

Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

Running R code on your phone... that is definitely magic!!

webR also makes it super easy to create #rstats learning resources that students can work with using just a browser, no install drama needed.

Grad programs often don't teach folks how to write good reviewer reports. Here are some resources:

1. @brendannyhan.bsky.social review checklist: thepoliticalmethodologist.files.wordpress.com/2016/02/tpm_...

2. "How to Write an Effective Referee Report": aeaweb.org/articles?id=...

What else?

How insane is it that openai asks for BIOMETRIC information for using its API with the o3 model?! Asking me to take a selfie and upload personal documents. Anthropic, here I come #dataskyence

Something you might find helpful is ggview::canvas() for setting the in RStudio viewing pane to be in the proportions you intend to export in. So it should look the same as a saved figure.

A little while ago I saw a really beautiful colour palette/colour science post. It was something to do with capturing pastel/water colours and transformations to the colourspace. I can't for the life of me remember what is was called, does anyone remember this? #rstats

Very very interesting and looking forward to reading it in full
1000 low income adults were randomly selected to receive $1000/month for 3 years, with a control group receiving $50/month over that same period. Many of them had children in the household. How did it affect how they parented and their kids’ outcomes? www.nber.org/papers/w34040

#rstats and TeX friends: what are your best takes on how to nicely size and place figures in academic articles? I spend time curating my #dataviz but then I default to big page-wide plots that end up automatically at the bottom of the document. Any tips/resources?
