Ewing model (in statistics)

The Ewing model is a statistical approach used to analyze and predict how certain variables, like healthcare costs or energy consumption, change over time or across different groups. It combines mathematical functions to capture different aspects of the data: some parts may increase or decrease steadily, while others might fluctuate or grow at varying rates. By fitting this model to data, analysts can better understand patterns, make forecasts, and identify factors influencing the outcomes, aiding decision-making in fields like economics, healthcare, or engineering.
