Predictive Modeling in Multidimensional Databases
- Predictive modeling: Predict data values or construct generalized linear models based on the database data
- One can only predict value ranges or category distributions
- Method outline:
- Minimal generalization
- Attribute relevance analysis
- Generalized linear model construction
- Prediction
- Determine the major factors which influence the prediction
- Data relevance analysis: uncertainty measurement, entropy analysis, expert judgement, etc.
- Multi-level prediction: drill-down and roll-up analysis
