pcc(y_preds, y_trues, err_default=0)

Pearson Correlation Coefficient (PCC)

Parameters:

• y_preds (Union[_SupportsArray[dtype], _NestedSequence[_SupportsArray[dtype]], bool, int, float, complex, str, bytes, _NestedSequence[Union[bool, int, float, complex, str, bytes]]]) – Predicted values

• y_trues (Union[_SupportsArray[dtype], _NestedSequence[_SupportsArray[dtype]], bool, int, float, complex, str, bytes, _NestedSequence[Union[bool, int, float, complex, str, bytes]]]) – True values

• err_default (float) – Value to return if PCC computation fails. Defaults to 0.

Return type:

float

Returns:

PCC between predicted and true values
