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
