PCC (Pearson Correlation Coefficient)
This section describes PCC (Pearson Correlation Coefficient) as a metric to evaluate the performance of a continuous prediction model.
What Is PCC (Pearson Correlation Coefficient)? - PCC (Pearson Correlation Coefficient) is a commonly used metric to evaluate the performance of a continuous prediction model. PCC measures how well predicted values are correlated to actual values.
Given a prediction model and a set of test samples, the PCC of the model on the test set is defined below:
where:
PCC can also be expressed as:
where:
