1) Write down the equation of the model using

2) Test whether the model is useful for predicting risk.

3) Conduct a test to determine if risk depends on blood sugar concentration.

4) Madam Z is 60 years old with blood sugar concentration 6 mg/dL. Classify her into one of the two risk categories. (Cut-off = 0.5)

An inexperienced medical doctor developed a regression model to help him classify patients as either 'high risk' or 'low risk' based on their AGE (in years] and bleed sugar CGNcentration {in mgfdl}. Using past data, the following model was developed : - -2 Log \"39.3mm . likelihood R S. were Step 1l AGE GUN Constant . e. Verieble{e} entered on step 1: AGE, CON. Let ' be the estimated chance that a patient belongs to the 'high risk' category. a] Write down the equation of the model using .ti'. b) Test whether the model is useful for predicting risk. c] Conduct a test to determine if risk depends on blood sugar concentration. d] Madam Z is 50 years old with blood sugar concentration 5 mgde. Classify her into one of the two rislr. categories. [Cut-off = 0.5]
