Both the numerator and denominator coefficients of the model are treated as free parameters in the process of optimisation. The method has a built-in stability-preserving feature. The problem of formulating the ISE is circumvented by introducing a set of equality constraints.eninfo:eu-repo/semantics/closedAccess[No Keyword Available]Article15115358WOS:00018930510000814
