Abstract

In this paper, second order slope rotatable design (SOSRD) under tri-diagonal correlated structure of errors using balanced incomplete block designs (BIBD) is suggested by following the works of Das (2003a, 2003b). Further, the variance of the estimated slopes for different values of the tri-diagonal correlated coefficient gif.latex?\rho (-0.9 to 0.9) for “ gif.latex?\nu factors 3 to 8” using BIBD is studied and observed that for some factors SOSRD under correlated structure of errors using BIBD has less number of design points than the corresponding SOSRD under tri-diagonal correlated structure of errors using central composite designs (CCD).
