Abstract

In this paper, an empirical study of second order rotatable designs under tri-diagonal correlation structure of errors using central composite designs is suggested. Further, we study the variance function of the estimated response for different values of tri-diagonal correlation coefficient and distance from centre (d) for “v factors ”.

Keywords

second order rotatable designs (SORD), robust SORD, tri-diagonal correlation structure of errors.
