Epistemic and aleatory

WebProfessor Jeremic's primary research interests are related to modeling and simulation of static and dynamic, inelastic, deterministic and probabilistic behavior of civil engineering objects. Focus is on development and use of methods that reduce modeling, epistemic uncertainty, and that propagate parametric,aleatory uncertainty. WebAleatory uncertainties are generated by intrinsic factors such as studying a sample rather than the whole population and the source of epistemic uncertainties is extraneous such as limitations of knowledge. These uncertainties inflict all the findings in empirical medical research, but they are rarely appreciated. This article highlights these uncertainties and …
