Venkata Sita Rama Anjaneyulu, G: On Second and Third Order S

Response Surface Methodology is a collection of mathematical and statistical techniques useful for analyzing problems where several independent variables influence a dependent variable or response and the goal is to find the product mix to optimize this response. As the estimation of slope of response surface occurs frequently in practical situations,. The authors have introduced the concept of embedding and constructed v dimensional second order slope rotatable from a known (v-1) dimensional second order slope rotatable using embedding techniques. Group-Divisibility in Second Order Slope Rotatable s (SOSRD) is also introduced and constructed various s in view of its practical applicability. As all existing second order slope rotatable s are five level s, the authors constructed second order slope rotatable s with factors each at four levels using balanced incomplete block s and central composite type points. They also introduced and constructed the Third Order Slope Rotatable s (TOSRD) over an axial direction using Central Composite s and Doubly Balanced Incomplete Block s
