Overall statistics across all molecules studied and all methods. Columns indicate median mean absolute relative error (MARE in kcal/mol), median R2 correlation, median Spearman correlation, and median single-core CPU time in seconds. MARE, R2, and Spearman correlation are relative to the DLPNO-CCSD(T)/cc-pVTZ baseline. Ranges indicate 95% confidence intervals for the median metrics established by bootstrap sampling.
