For the other barrier height data sets, error statistics vary more widely from one functional to another, with MAEs ranging from 1-9 kcal/mol. Standard deviations (Tables ) are smaller than 2 kcal/mol except for the B(60)LYP+D3, B(70)LYP+D3, and BLYP+D3 functionals, where they range from 2.5-3.0 kcal/mol. Those three functionals will emerge as the least accurate of those examined here, and they are included mostly to set goalposts on the performance of B(α)LYP. Even so, the spread of the errors is sufficiently tight so that MAEs provide a reasonable way to analyze the error statistics.
