xG estimates chance quality; it does not promise the actual score. This page does not display an xG value unless the authorized source supplies it.
Calibration compares stated probabilities with observed outcome frequency over an adequate sample. One match row cannot establish that a model is calibrated.
For a binary outcome, the Brier score averages (p − o)²; lower is better. OddNexo does not claim a site-wide score without a verified evaluation sample.
A model can estimate probabilities for outcomes such as 1X2, goal totals or BTTS. The output is an uncertain estimate, not a guaranteed final score or profit claim.
Use a pre-defined evaluation sample and scoring rule, then compare against a baseline. Accuracy, calibration and Brier score remain not_verified here until that evaluation is published.
