Refer to Exhibit 1. Run the script you saved for Discriminant Analysis in Question 5 and select the red triangle option Discriminant Method >Quadratic Different Covariances. This will change the "Discriminant Analysis Method" used in the analysis. Keep your eye on misclassification rates on validation sets. (You may want to hide Discriminant Scores table to see the changes). . The discriminant method Linear v provides a better misclassification rate. WHY? (Just think about this) Now, use the red triangle option Specify Priors>Proportional to Occurrence . Specifying prior probabilities using proportions of class occurrences in the data set provides a better misclassification rate
