List of uncertainty types.
See the OPENSTUDIO_ENUM documentation in utilities/core/Enum.hpp. The actual macro call is:
((Aleatory))
((Epistemic))
);
Aleatory uncertainty refers to the case where the uncertainty is inherent to the variable, that is, truly stochastic. Epistemic uncertainty arises from a lack of knowledge–that is, with more research this type of uncertainty should be removable. Sometimes the uncertainties are layered. For example, the mean and variance of an aleatory uncertainty may be modeled as epistemic uncertainties.
