calculate_r2

cinnabar.stats.calculate_r2(y_true: ndarray, y_pred: ndarray) → float

Compute R^2 between true and predicted values.

Note

R^2 is calculated as the square of the Pearson correlation coefficient between true and predicted values.

Parameters:

• y_true (ndarray with shape (N,)) – True values

• y_pred (ndarray with shape (N,)) – Predicted values

Returns:

r2 – R^2 between true and predicted values

Return type:

float
