The use of statistical or machine-learning models to estimate future or unknown outcomes from available data.

Predictive models let a business act before outcomes occur, for example prioritizing leads likely to buy, customers likely to churn or orders likely to be late, which focuses limited resources where they matter.

A subscription company trains a gradient-boosted model on 24 months of usage, support and billing data to score churn risk weekly, and its success team contacts the 5% of accounts with the highest scores.

Models learn from historical patterns and degrade when behavior, products or markets change. Overfitting, data leakage and biased training data produce misleading predictions, and a correlation-based score does not show what causes the outcome.

A predictive model maps input features to a target outcome using methods such as linear or logistic regression, decision trees, gradient boosting or neural networks. Historical data is split into training, validation and test sets, or evaluated with cross-validation, to estimate performance on unseen cases. Results are measured with metrics such as accuracy, AUC, precision, recall or mean absolute error, and monitored for drift after deployment.
