           | Do drunk french people buy kebabs? In my city one central

           | There's one obvious place to go around here for a good kebab,

           | tell it's the best place for a kebab is how late it's open

           | still doing enough business to justify remaining open.
           | 
           | The best place for pizza in my city is very close to a train
           | station but that's a total accident, they park (it's a van,
           | no really, best pizza in the city but they hated owning a

             | Is that a quality signal, or just a sign they don't mind
             | selling to people going back from parties, in various
             | stages of being drunk? I always assumed the latter. Few

             | trickle of customers who literally have nowhere else to eat

         | I actually came to a different conclusion than the author. Here
         | is the way I'm thinking about the presented statistics:
         | 
         | 1. There is 17 Kebab shops (out of 400 samples) with a google
         | review lower than 3 stars. Let's call them "bad kebabs".
         | 
         | 2. All those "bad kebabs" actually located within 500m from the
         | nearest station. No kebab located in further than >500m is bad.
         | 
         | 3. So if you've ever gotten a bad donor kebab, we can safely
         | assume that you have purchased it from a kebab shop near a
         | train station.
         | 
         | Maybe there are so many kebab eaters near a train station that
         | a mediocre kebab offering becomes profitable?

       | for solving the problem of reviews not representing kebab taste,
       | you can put reviews through the llm and ask it silple question -
       | does it say that kebab is good or bad, or it is not about the
       | taste at all
       | 
       | given then a set of labeled reviews, you can very reliably devise

       |

       | Hi there, "OP" here.
       | 
       | First off, it's been fun to see this post spread across the
       | interwebs since I first wrote it one caffeine-fueled day just
       | over a week ago (first Meneame, now here) and for the heck of it,
       | I thought I would clarify a few things;
       | 
       | This post was (sortof) a meme. Sure, I "understood the
       | assignment" and performed the quick "study" ("analysis" might be
       | more fitting) for the sake of the original post over on r/gis,
       | but I was surprised to see how seriously others took the matter.
       | I suppose good kebabs are a serious matter.
       | 
       | As others have pointed out, a linear correlation was likely a
       | flawed approach for testing the "hypothesis". Though the original
       | wording from the french post which first brought this to my
       | attention implied as much, in hindsight it's likely that the
       | kebab shops within a certain radius are on average worse than the
       | rest.
       | 
       | Also, it seemed that Paris was one of the worse study areas. It,
       | apparently, has some very good kebab shops that just so happen to
       | be in close proximity to train stations.
       | 
       | I suppose I need to start working on part 2....

           | This sounds like the correlation _appears_ because of you

           | 
           | I've been reading up on collider bias on Wiki and pondering
           | the examples[0] - restaurants, dating, celebrities - and the
           | way I see it, the biased statistics is still true for whoever
           | is doing the classification (person visiting fast-food
           | restaurants, or looking for a date), and if their selection
           | (taste) generalizes, it might also carry over to the general
           | population.
           | 
           | I feel the restaurant example from Wiki, with its associated
           | image below, is worth discussing:
           | 
           | https://en.wikipedia.org/wiki/Berkson%27s_paradox#/media/Fil.
           | ..
           | 
           | "An illustration of Berkson's Paradox. The top graph
           | represents the actual distribution, in which a positive
           | correlation between quality of burgers and fries is observed.
           | However, an individual who does not eat at any location where
           | both are bad observes only the distribution on the bottom
           | graph, which appears to show a negative correlation."
           | 
           | This feels wrong to me. Why is the regression line nearly
           | horizontal when, eyeballing the graph, a _nearly vertical_
           | one would fit better _and_ capture an even stronger positive
           | correlation between qualities of hamburgers and fries? In
           | fact, I 'm tempted to even throw away the leftmost and
           | rightmost points on the lower panel as outliers.
           | 
           | Anyway, this example assumes the bad/bad restaurants are not
           | visited by the subject - however, if we take your scenario
           | where bad/bad restaurants quickly go out of business, then
           | it's _the market_ that _creates_ the correlation between
           | those two hypothetically independent qualities, so as long as
           | we 're talking real world and not some imaginary spherical
           | restaurants in frictionless vacuum, it would be fair to say
           | the correlation exists (and that the causal mechanism behind
           | it is market selection).

       | 
       | ... I had an ex who was a huge clam chowder fan, so she did her

       | 
       | Her completely unscientific finding was that the very best

       | 
       | It makes perfect sense to me: if people come to your restaurant
       | because of its location, you don't put much effort into quality.
       | If you're far from the walk-in traffic, you need to do something

       | I was actually expecting to see data that would refute the

       | was expecting.
       | 
       | The assumption that I had made was, "More foot traffic = more
       | customers = more reviews = higher overall rating". I was
       | expecting to see a very high score close to train stations, and a
       | hard slope the further you went from stations. My thinking was
       | that location would _heavily_ favor the rating, both in terms of
       | convenience for customers, and in terms of non-Parians eating the
       | food, because they are on vacation, traveling, etc. as the author
       | had mentioned. I figured that if they are in higher spirits, they
       | would leave higher reviews.
       | 
       | After seeing the results, it does make me wonder if this might
       | have still played a role, but to a lesser degree? Hard to say,
       | given how scattered it all is. Botting really does ruin metrics
       | like this.
       | 
       | Personally, I think, it would be interesting to see something
       | like the following in part 2:
       | 
       | 1) Distance from station _and_ proximity of kebab shop to bars
       | /nightclubs. Perhaps someone who is drunk, and plans on taking
       | the metro back to a hotel is likely to think a kebab is far
       | better, compared to one who is further away from heavy drinking
       | and further away from transportation. Both of those things being
       | removed would make me think the overall review would be lower,
       | but I think the actual ratings would be far more _accurate_ , and
       | more likely given by Native Parisians (assuming it's by a
       | neighborhood, or whatever.)
       | 
       | 2) It would be interesting to see what the impact is, in terms of
       | _amount_ of reviews reviews, the further away a kebab shop is
       | from a station.
       | 
       | For example: If we are to assume that kebab_1 and keba_2 both
       | open within six months of one another, but one is 1km from a
       | station, while the other is almost on the platform, how much will
       | that impact the number of reviews received?
       | 
       | 3) Finally, it might also be interesting to hear what other food
       | review websites that might offer this type of information. I
       | assume the French have _at least_ one French-centric social media
       | platform for food reviews, which you can (hopefully) grab data
       | from. How does that sites info compare to Google?
       | 
       | 3a) Other nations food review sites might be interesting, too. My
       | understanding is that Iran and Turkey are both very passionate
       | about kebab, I could imagine them have thorough reviews of
       | Parisian kebab shops. I could also see Japan having a pretty
       | passionate food review site, given how crazy the Japanese can get
       | for France, Paris in particular. I.e.
       | https://en.wikipedia.org/wiki/Paris_syndrome
       | 
       | 4) Perhaps there would be some interesting datapoints to pull out
       | based on places that have closed permanently. That is, "Is a
       | kebab shop that is close to a station more likely to stay open,
       | or close down?"
