Results of the linear regression of the predicted interaction energy data for eight largest dimers from the Set50-50. The model is $\left\{y\right\}=a\times \left\{x\right\}+b$, where $\left\{x\right\}$ is shorthand notation for the canonical CCSD(T)/CBS data, and symbols $a$, $b$, $\sigma$ and $\left|r_{\mathrm{m}\mathrm{a}\mathrm{x}}\right|$ stand for a slope, intercept, standard deviation of residuals and an absolute value of the maximum residual of this model, respectively.
