Webinar: Building Better Models in Multiple Regression

The typical approach to building a regression model involves the removal of terms with p-values greater than .05 or 0.1, resulting in models that are good, but not necessarily best. In this webinar, we review metrics and methods that maximize the chance of building the best possible model, with important terms kept in the model, unimportant terms removed from the model, and provide maximum prediction accuracy. SigmaXL software will be used to demonstrate these methods.


  • Model building metrics:
    • p-values
    • Akaike Information Criteria (AICc)
    • Bayesian Information Criteria (BIC)
  • Automatic model building methods:
    • Forward Selection
    • Backward Elimination
    • Mixed Forward/Backward
    • Best Subsets
  • Validation of models:
    • Predicted R-Square
    • K-fold Cross Validation R-Square
  • Example/Case Study
