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

intermediate Published 23 May 2026
Action Steps
  1. Build a logistic regression model using a dataset of your choice
  2. Calculate the accuracy score of your model
  3. Create a confusion matrix to evaluate true positives, false positives, true negatives, and false negatives
  4. Compute precision, recall, and F1 scores to assess model performance
  5. Plot the ROC curve and calculate the AUC score to evaluate model reliability
Who Needs to Know This

Data scientists and analysts can benefit from this guide to improve their model evaluation skills, while machine learning engineers can use it to develop more robust models

Key Insight

💡 Accuracy scores can be misleading, and using additional metrics provides a more comprehensive understanding of model performance
