conn2res.performance.r2_score

conn2res.performance.r2_score(y_true, y_pred, sample_weight=None, multioutput='uniform_average', **kwargs)

Coefficient of determination of the regression R^2.

Parameters:

• y_true (numpy.ndarray) – Ground truth target values.

• y_pred (numpy.ndarray) – Predicted target values.

• sample_weight (numpy.ndarray) – Sample weights.

• multioutput (str) –

  Defines aggregating of multiple output scores:

  ‘raw_values’ : Returns a full set of scores in case of multioutput input.

  ‘uniform_average’ : Scores of all outputs are averaged with uniform weight.

  ‘variance_weighted’ : Scores of all outputs are averaged, weighted by the variances of each individual output.

Returns:

score – A floating point value or an array of floating point values, one for each individual target.

Return type:

float or ndarray of floats.
