Figure 2.3: Two input sets containing 70 samples generated according to the MC method
respective the LHS method. Both parameter A and B were assumed to distribute uniformly
between 0 and 1.

Uncertainty Analysis
The total uncertainty of the calibration factor consists of two components: the combined uncertainty of the detector efficiency calculation and the uncertainty from the
calculations. According to Equation 2.32, the total uncertainty can be determined by
u2total = u2detector + u2calculation .
(2.37)
The combined uncertainty of the detector efficiency is a Type B uncertainty and was
calculated to be 4% [6]. In order to determine the uncertainty from calculations, the
following two concepts are useful.
