Combining AE ratings with a Neural Network
wordpress.com
I have recently been working on my AE horse ratings, looking at a new and perhaps more productive way of combining the AE values assigned to each attribute, than simply multiplying them together. This blog entry will examine my work with a neural network approach, the Weka freeware software and the results I have achieved.

Liverpool are over performing their expected points, does that make them lucky?
Hoops in Motion: The Evolution of Pace in Basketball
substack.com - Sidney
In the fast-evolving landscape of professional basketball, particularly within the NBA, the concept of "pace" has surged to the forefront as a critical element shaping the modern game. In this article we use seconds per possession as a measure of pace. This measure not only quantifies the speed of play but also illuminates how teams strategize to maximize their scoring opportunities within the constraints of the shot clock.
Video Assistant Referee and Home Field Advantage: Implications for Referee Bias
ssrn.com - Camilo Abbate, Jeffrey Cross, Richard Uhrig
Until recently, soccer referees operated with minimal technology assistance. Following the successful introduction of communication devices and goal-line technology, as well as the use of video review systems in various other athletic competitions, soccer leagues around the world implemented Video Assistant Referee (VAR) technology to further reduce mistakes and improve referee performance. This paper investigates the effect of Video Assistant Referee systems on home field advantage in soccer using a staggered adoption difference-in-differences framework and data from 16 leagues between 2009 and 2019. We find that the implementation of VAR had negligible effects on home field advantage despite impacting various match statistics for both home and away teams. These results have important implications for the impact of referees on home field advantage, especially in light of recent literature.
