(en) This note investigates the various ways of specifying the state adjustment model in discrete time. It is shown that the value of the structural parameters depends on the discrete approximation, although the estimating form remains unchanged. Consequently, it is important that analysis involving those parameters be carried out using estimates obtained in a mutually consistent specification of the model; failures to do so may result in erroneous conclusions.
