Predictive analysis

Overview

Predictive analysis is using historical numbers to make predictions about future numbers. It is finding patterns in historical information to create a model of the data and persist those patterns into the future. (1)

Prediction models are meant to forecast individual drivers. E.g. we're able to forecast revenue by segment, we backtest revenue
