Description

Epistemic uncertainty is uncertainty due to lack of knowledge.

In Dakota, epistemic uncertainty is characterized by interval analysis or the Dempster-Shafer theory of evidence.

Note that epistemic uncertainty can also be modeled with probability density functions - similarly to aleatory uncertainty Dakota does not support this capability.
