A Study on Second Order Rotatable Designs under Tri-diagonal Correlated Structure of Errors Using a
In this paper, a study on second order rotatable designs under tri-diagonal correlated structure of errors using a pair of balanced incomplete block designs is suggested. Further, the variance function of the estimated response for different values of tri-diagonal correlated coefficient and distance from centre for ( - factors) are studied.
