Lecture 9 – Bivariate Association
Each column’s frequency distribution is called a conditional distribu-
tion of Y.
The five-step model is calculated using chi-square.
Prediction rule: Predict that all cases fall the largest category.
Where E1 is the number of prediction errors without knowing X.
And E2 is the number of prediction errors knowing the distribution
Gamma and its associated statistics can have a PRE interpretation.
