Formulations from Kobayashi K. and Salam M.U. (2000) :

Squared bias
\( \mathsf{SB} = (\bar x - \bar y)^2 \)
Squared difference between standard deviations
\( \mathsf{SDSD} = \left(\mathsf{SD}_x - \mathsf{SD}_y \right)^2 = \left( \sqrt{\frac{1}{n}\sum\limits_{i=1}^{n}{(x_i-\bar x)^2}} - \sqrt{\frac{1}{n}\sum\limits_{i=1}^{n}{(y_i-\bar y)^2}} \right)^2 \)
Lack of correlation weighted by the standard deviations
\( \mathsf{LCS} = 2 \ \mathsf{SD}_x \ \mathsf{SD}_y (1-r) \)
\( r = \left[ \frac{1}{n}\sum\limits_{i=1}^{n}{(x_i-\bar x)(y_i-\bar y)} \right] / (\mathsf{SD}_x \mathsf{SD}_y) \)
