“…Many models that appear in the engineering literature have multiple types of response variables (e.g., temperatures, pressures, concentrations, yields). If the model form is complicated, or the data available are not sufficiently informative, estimating all of the unknown parameters may be very difficult or even impossible (e.g., Ben-Zvi et al, 2004;Kou et al, 2005a,b). In these situations, there are often many competing SMs that could be used, depending on the simplifying assumptions that are made and the subset of parameters that are to be estimated (Thompson et al, 2007(Thompson et al, , 2009Chu and Hahn, 2008;Lund and Foss, 2008).…”
