Stop Trusting Your Accuracy Score: A Practical Guide to Evaluating Logistic Regression Models
📰 Dev.to · Gervais Yao Amoah
Learn to evaluate logistic regression models beyond accuracy scores using confusion matrices, precision, recall, F1, and ROC/AUC metrics
Action Steps
- Build a logistic regression model using a dataset of your choice
- Calculate the accuracy score of your model
- Create a confusion matrix to evaluate true positives, false positives, true negatives, and false negatives
- Compute precision, recall, and F1 scores to assess model performance
- Plot the ROC curve and calculate the AUC score to evaluate model reliability
