See all my videos at https://www.tilestats.com/ In this second video about logistic regression, we will see how we can use it as a classifier (a machine learning technique) to predict if someone has a disease. The video consists of: 1. Some basics 2. How to classify with a cutoff value (02:15) 3. How to calculate sensitivity and specificity and the ROC curve (08:20) 4. How to validate the model (14:00) 5. Use more than one explanatory variable (15:18) 6. Model selection and predictions (20:39)
