Sah inversely proportional to weighted
Webbut are inversely proportional to the uncertainties in the individual xi (inverse variance weighting, Case II), this approach yields an unbiased estimate of the uncertainty in the weighted mean. So far, so good. However, big problems can arise if these formulas are used in Case I, when the uncertainties in the WebThe “balanced” mode uses the values of y to automatically adjust weights inversely proportional to class frequencies in the input data: n_samples / (n_classes * np.bincount (y)). For multi-output, the weights of each column of y will be multiplied. y{array-like, sparse matrix} of shape (n_samples,) or (n_samples, n_outputs)
