Start Free TrialHow to Use the Enhanced Model Evaluation Metrics Calculator
Choose your input method: enter confusion matrix values directly or provide actual vs predicted arrays. The enhanced tool now calculates comprehensive evaluation metrics including Matthews Correlation Coefficient, NPV, and FPR, with export capabilities and visual confusion matrix display.
Understanding All Model Evaluation Metrics
Enhanced model evaluation metrics for comprehensive model assessment:
- Accuracy: Overall correctness of the model (TP+TN)/(TP+TN+FP+FN)
- Precision: Quality of positive predictions TP/(TP+FP)
- Recall (Sensitivity): Model's ability to find all positive cases TP/(TP+FN)
- F1-Score: Harmonic mean of precision and recall
- Specificity: Model's ability to correctly identify negative cases TN/(TN+FP)
- Balanced Accuracy: Average of sensitivity and specificity
- Matthews Correlation Coefficient (MCC): Correlation between predictions and actual values
- Negative Predictive Value (NPV): Probability that negative predictions are correct
- False Positive Rate (FPR): Proportion of actual negatives incorrectly classified as positive

Frequently Asked Questions
Q. What is Matthews Correlation Coefficient (MCC)?
MCC is a balanced measure that considers all four confusion matrix categories. It returns a value between -1 and 1, where 1 indicates perfect prediction, 0 indicates random prediction, and -1 indicates total disagreement.
Q. When should I use Balanced Accuracy vs Regular Accuracy?
Use Balanced Accuracy when dealing with imbalanced datasets. It gives equal weight to sensitivity and specificity, providing a more reliable measure for imbalanced classes.
Q. What formats can I export the results in?
You can export results in CSV (for spreadsheets), JSON (for APIs/programming), and TXT (human-readable format) to suit different use cases and workflows.
Q. What's the maximum dataset size the tool can handle?
The tool can handle up to 10,000 data points for optimal performance. For larger datasets, consider using the confusion matrix input method or processing in batches.
