Mapping between the econometric and the RDPP-SF approach.

Econometric model RDPP-SF method
Set of DMUs Design plan (DoE)
DMU(i) Run, i, in the DoE
Panel/cross data Replicated/non-replicated dataset
vi: random variation Statistical random variation
ui: technical inefficiency Non-random variation (measurement of robustness in the process)

Metric for the RDPP-SF*: (H0 : γ = 0 vs. H1 : γ > 0) where γ=σu2σv2+σu2, Rejected H0 at α = 5% level if the Likelihood Ratio (LR) exceeds χ1,2α=10%2.

*

Hypothesis test on robustness. If it is proven statistically significant we should reject the hypothesis saying that the process is fully robust, i.e., under statistical control, solely.
