Reply to comment by diffraction-limited in [OC] Relation between the square meter price of an apartment and distance from Notre Dame de Paris in Paris and Ile-de-France by sudu1988

Yeah, I've tried and inverse square law didn't word well. On the original article you can find more info https://damovs.com/rental-market-of-apartments-in-paris-in-2023/

I read the article. What did not work? Or why do you think the exp formula in the article did work?

Well, the results looked much more off. But you are right, I should add some information on the mean squared error. In my article I didn't wanted to shock people with it, because it's kind of more informative post.

Yeah i get that, but for me that would be the interesting part. Making a model is just one part, choosing if the model is correct is a whole different story :) And i still think that adjusting an inverse square model might be worth trying, no? The price is based on available space, and this correlates with a square and not an exponential function. Not sure why I feel so strongly about that, sorry:)

No worries. Will give it another try later. It's maybe really worth it.

Very cool, if you can expand this to other cities that would be very interesting

Also, if you could plot this against the mass of garbage outside each, that would be great /s

Price probably falls off faster than inverse square. The available space grows quadratically, but as you get further you lose more prestige, proximity with important landmarks etc.

True. But even if you use some mix of polynomials it might be still better to argue why, rather than using an exponential here no?

Sure! Deciding which model to use a posteriori based on the shape of the data is definitely not ideal.

Yeah. That's what my students do. Love to discuss with then why it's not the way forward, haha

With this much data I would just fit a flexible regression like LOESS

Anyway to fit it to a Zipf curve?

I will try to redo the plot with the suggestions posted here.
