Matthews Correlation Coefficient (MCC) Calculator

Calculate Matthews Correlation Coefficient (MCC)

Easily calculate the Matthews Correlation Coefficient (MCC) to assess the quality of your binary classification models. This balanced metric, crucial in machine learning and data science, accounts for true positives, true negatives, false positives, and false negatives, providing a comprehensive measure of prediction performance. Use our free online calculator for quick, accurate results.

Formula:

The Matthews Correlation Coefficient (MCC) is calculated using the following formula:

MCC = (TP × TN - FP × FN) / √((TP + FP) × (TP + FN) × (TN + FP) × (TN + FN))

Where:

  • TP = True Positives (Correctly predicted positive cases)
  • TN = True Negatives (Correctly predicted negative cases)
  • FP = False Positives (Incorrectly predicted positive cases, Type I error)
  • FN = False Negatives (Incorrectly predicted negative cases, Type II error)
