My new football-forecasting research, Dominant Below, Drowning Above, is now available.
Why this matters
Promotion is a clean forecasting problem: newly promoted clubs are the strongest teams from the lower division, but immediately become among the weakest teams in the league above. The study uses this boundary to ask whether a model trained on the whole league can read promoted clubs as well as it reads established clubs.
Main result
The same model performs well for established clubs but much less well for promoted clubs. In the study, survival forecastability is about 0.80 AUROC for established clubs and about 0.57 for promoted clubs, close to the boundary where prediction becomes weak.
