Abstract

Abstract Parameter estimates obtained by identification procedures may or may not be measurements of attributes in the system under study. It is argued that both a valid model and a well-posed identification problem are necessary conditions for such estimates to be considered measurements. Empirical and theoretical methods are presented for testing these conditions. Finally, some possible sources of uncertainty are highlighted and methods for treating this uncertainty are discussed.
