Question: Expanded Uncertainty Determination


"Welch-Satterthwaite formula":
With the package "ScientificErrorAnalysis" is easily calculated, the combined uncertainty of a mathematical model M = f (x1, x1, .. xn). But if I need to know the components of the calculation model uncertainty becomes very repetitive. For example to calculate the expanded uncertainty should be calculated uncertainty components model for using the Welch-Satterthwaite formula ". Which determines the effective degrees of freedom υeff:


In the attached sheet present how we made ​​these calculations. To determine the uncertainty contributions of each variable we have made a very repetitive process, nothing fancy and didactic. Could guide me to improve so doing.
