In this post I continue my exploration of the [1]. Yet here I will slowly start moving away from the course of the original manuscript.

The original manuscript [1] also explores unbiased decision model. In the unbiased model users make decision only based on the attractiveness of the recipient. For some reason I do not feel that unbiased decisions are realistic (though only the data can tell this) and thus I will not explore the unbiased model.

The original manuscript is also concerned with another important feature of the dating apps: visibility of the users. It is not likely, but still somewhat possible, that I will also follow in this direction.

Still this post is within the scope of the original manuscript, as when reading it I wasn't able to understand whether static or dynamic model is considered. So here I present you a dynamic biased decision model.

Previous summer I have stumbled upon an interesting manuscript [1], which explores dating app dynamics (?) from the perspective of statistical physics. I am not sure about the "dynamics" part, as to me it appears to be more "static" than "dynamic", but nevertheless the manuscript caught my attention and I would like to discuss some related questions in the next few posts.

In this post we will take a look at static interpretation of the "biased decisions" model from the manuscript [1].

Few years ago I have played around with Premier League data and created a simple model of EPL 2000/2001 season. Let us put it to the test and predict upcoming FIFA World Cup in 2022?

Note that my predictions here should not be treated as a betting advice. It is just a quick fun exercise for me.

Can probabilities be negative? Yes, whenever information behaves in quirky ways in quantum systems. Video comments seem to suggest that similar observations can also apply in traffic.

For a detailed explanation on when using negative probabilities might make sense, watch the video by Steven G below (it took part in a "Summer of Math Exposition" 2021 contest).

FiveThirtyEight has an interesting column, Riddler column, which I follow with great interest. In this post we will revisit boring basketball game problem from analytical perspective. Though we will cheat a bit and use Python to do the algebra for us.
