statistical models
Data-driven mathematical representations
Statistical models are mathematical frameworks that represent relationships within data, using equations and assumptions to describe patterns, make predictions, or test hypotheses.
They range from simple linear regression to complex machine learning algorithms.
The statistical model predicted customer behavior with 85% accuracy.
Scientists use statistical models to draw inferences from samples about larger populations, though all models simplify reality to some degree.
