Challenge Problems
Push your limits with advanced challenges
You have a logistic regression model that has a confusion matrix with the values: TP = 15, TN = 20, FP = 5, FN = 10. Calculate the model's accuracy and explain its significance.
💡 Hint: Use the total number of true results over the total number of all cases.
Given a logistic regression model's output probability of 0.65 for a new test case, discuss what classification it will yield and the implications of changing the threshold to 0.7.
💡 Hint: Always consider how threshold adjustments impact the sensitivity and specificity.
