This study also suggests, however, that parameters which cannot be calibrated based on empirical data will continue to be a major source of model uncertainty.
Furthermore, a probabilistic sensitivity analysis was conducted to explore the overall uncertainty by varying all major model parameters simultaneously using a random number generator and appropriate distributions.
This result indicates that even without model-data mismatch errors due in large part to transport model uncertainties, the biospheric signal acts as a major confounding factor in the detection of the FFCO2 signal during the summer months.
To identify model drivers and examine key areas of uncertainty within the model, one-way deterministic sensitivity analyses were conducted for all major model variables.
One might term this the "Major model".
Filtering with model uncertainties.
The estimation of these patterns, which is mostly done based on sparse observations and expert knowledge, is a major source for predictive model uncertainty.
In fact, Lukacz et al. (2007) argue that model weights and their ability to account explicitly for model uncertainty are major reasons why IT approaches should be highly favored over NHST (Richards et al. 2011).
The results show that length and modulus of granular piles are the two major sources of uncertainty and that the model uncertainty obtained from the interpretation of relevant sensitivities is smaller with the finite element model.
One major issue of the application of feedback control techniques is the effect of model uncertainty, such as boundary condition variation, on structural damage detection.
