Umalytic Model
How Umalytic Works
Statistical probabilities, not betting advice.
What Umalytic is
Umalytic is a pre-match tennis probability platform. It estimates the likelihood of each player winning a match based on historical data and match context. It does not provide tips, picks, or betting recommendations.
What a probability means
When Umalytic shows a probability, it is not predicting a certain outcome. It is measuring uncertainty.
For example, when the model assigns a 60% probability, matches with similar conditions have historically been won about 60% of the time.
Probabilities are evaluated using historical out-of-sample data.
Calibrated probabilities
The model is calibrated. This means that its probabilities are statistically consistent with real outcomes.
On average, the difference between predicted probabilities and observed frequencies is below 2.5 percentage points. This property is known as calibration and is essential for interpreting probabilities correctly.
What it does
- Estimates probabilities based on data
- Updates features with recent matches
- Accounts for surface, form, and match context
- Preserves uncertainty
What it does NOT do
- Does not guarantee winners
- Does not optimize for streaks or win rate
- Does not suggest bets
- Does not replace personal judgment
About metrics
Many sports platforms highlight accuracy or winning percentages. Umalytic focuses on probability quality instead.
A model can guess more winners and still provide misleading probabilities. Umalytic prioritizes statistical consistency over binary correctness.
Accuracy is not shown because it does not measure probability quality.
Transparency and versioning
Model transparency
Each probability is generated using a versioned model with fixed logic and calibration. Model versions are only updated after full historical evaluation.
Recent match data updates player features, but the model itself remains unchanged until a new version is released.
Model metadata will appear here once it is available.
Umalytic is an analytical tool. All decisions remain the user's responsibility.
