# The temporalized Massey's method

## TL;DR

This paper introduces a dynamic, temporal adaptation of Massey's rating method for sports teams, updating ratings after each match based on performance and opponent strength, and demonstrates its predictive accuracy using Italian soccer data.

## Contribution

It presents a novel temporalized version of Massey's method, integrating time dynamics into team ratings for improved predictive performance.

## Key findings

- The method achieves high foresight prediction accuracy on Italian soccer data.
- Temporalized Massey's method outperforms traditional static ratings.
- The approach effectively captures team performance dynamics over time.

## Abstract

We propose and throughly investigate a temporalized version of the popular Massey's technique for rating actors in sport competitions. The method can be described as a dynamic temporal process in which team ratings are updated at every match according to their performance during the match and the strength of the opponent team. Using the Italian soccer dataset, we empirically show that the method has a good foresight prediction accuracy.
