Comparison of relative deviation index for crude and quality controlled data. This plot compares the values for the relative deviation index ϑ(Δα p , Δβ q ) ρ calculated as the parameter change index ρ(p, q) varies. Values of ϑ(Δα p , Δβ q ) ρ produced by crude data are shown using blue lines and those corresponding to quality controlled data in red lines
