3.3 The Framingham Heart Study: Evaluating Risk Factors to Save Lives

3.3 The Framingham Heart Study: Evaluating Risk Factors to Save Lives

Quick Question

 

In the previous video, we computed the following confusion matrix for our logistic regression model on our test set with a threshold of 0.5:

  FALSE TRUE
0 1069 6
1 187 11

Using this confusion matrix, answer the following questions.

What is the sensitivity of our logistic regression model on the test set, using a threshold of 0.5?

Exercise 1

 Numerical Response 

 

What is the specificity of our logistic regression model on the test set, using a threshold of 0.5?

Exercise 2

 Numerical Response 

 

Explanation

Using this confusion matrix, we can compute that the sensitivity is 11/(11+187) and the specificity is 1069/(1069+6).
