Historic Soccer Analysis: Home is Where you Win

Besides the data I gathered for the soccer seasons in 2013 around the world, I also put together all seasons for England, Italy, Germany and Spain. The Big Four, as they are referred to. I was particularly interested, how the home field advantage changed over time, that is: Did the number of home wins increase or decrease over time? My educated guess was: It decreased.

Why Twitter Hates Math

I am bad at implementing stuff myself. So when it comes to gathering data, I always have to rely on some smart dude(tte) on the Internet to provide me fool proof tools to do my data gathering. Recently, i found a tool to get data from twitter in the most idiot proof way possible.

So i could finally gather data for my project: “How do people feel about math?”
To anticipate the outcome: Not very positive…

Proof: Wikipedia

“A mathematician is a machine for turning coffee [and wikipedia articles] into theorems” [A. Rényi]

In the last couple of weeks (or months, I lost track of space and time!) I tried to prove something. 



This “something” turned out not to be as trivial as I thought it would be and I had to invoke the power of a lot of mathematical concepts. Although I studied math, a lot of things were new to me (or I just forgot them) and I had to (re)learn quite a bit. Of course taking courses or reading books would be too time consuming, so I used Wikipedia as a reference (Disclaimer: Do not admit doing that in real life). Continue reading Proof: Wikipedia

Soccer Analytics Part 3: Transitivity of Soccer

“If Bayern Munich won 3:1 against FC  Barcelona and Borussia Dortmund won 3:0 against Barcelona, then Dortmund will win 6:1 against Munich.” We all did this calculations when we were younger! What we didn’t know back then is that we implicitly assumed a strong transitivity in soccer and therefore a high predictability of results. Because when we know that A beat B and B beat C, than we can be quite sure that A will beat C. But of course we all know that soccer does not work like that. But how transitive is soccer actually. That is, how often can we observe a triplet A beats B, B beats C and A beats C?
This entry will deal with this question and also compare the transitivity of soccer with other sports around the world.
