I am too young to get nostalgic (at least I pretend), but 10 years after the "Berlin Wall" paper and with 15 years newer data I realize two things: 1) The Berlin spatial structure did not change that much 2) how much more convenient it has gotten to collect land values 😀 @reddingecon.bsky.social

Last day of the @bsoeberlin.bsky.social course in Quantitative Spatial Economics. What a great cohort! If you spot any of these faces on the job market, don't hesitate! Thoroughly impressed by their coursework—the nerdy discussions during the lectures: priceless! 🫰 sites.google.com/view/bqse/bq... f

Yep, I agree and thought it would be nice to show. With a spatially random holdout sample, RF clearly wins as expected...

OLS, unlike RF can extrapolate spatial trends! Already looking forward to teaching it!

Preparing my Applied Econometrics course @humboldtuni.bsky.social using
@gaborbekes.bsky.social
great textbook gabors-data-analysis.com. Added a nerdy exercise to the application of Random Forrest to predicting Airbnb prices. OLS beats Random Forrest when predicting outside a spatial window!

The 2025 season of the @bsoeberlin.bsky.social QSE course is running. Here is how it is going: sites.google.com/view/bqse/bq.... And here is my latest toy for the current cohort and anyone else. Maybe the simplest way of computing travel time matrices, designed for noobs! github.com/Ahlfeldt/TTM...
