Abstract
In this paper, measure of slope rotatability for second order response surface designs using pairwise balanced designs under intra-class correlated structure of errors is suggested and illustrated with examples.
Keywords: Response surface design, slope-rotatability, intra-class correlated structure of errors, pairwise balanced designs, weak slope rotatability region.
