DASAR

All-NBA Predict #21 - Classifying All-NBA Players (Part III - Quadratic Discriminant Analysis)

Last post, we reviewed a few different topics

  • Gaussian distribution
  • Multivariate gaussian distribution
  • Linear discriminant analysis

We left off feeling a bit unsatisfied with LDA because were were getting 92% / 69% accuracy in prediction for all-NBA players and non all-NBA players respectively. 1,073 more words
