Following [14] for a Quartic polynomial, P(x) = [a.sub.0] + [a.sub.1] x + [a.sub.2] [x.sup.2] + [a.sub.3] [x.sup.3] + [a.sub.4][x.sup.4].
Since the larger values of [R.sup.2] and [R.sup.2.sub.adj] and the smaller values of RE and RMSE indicate a better fitness of the RS models, it is found that compared to other response functions the quartic polynomial functions provide the best approximation on the column's responses and therefore should be used for optimum design.
