An empirical study on second order slope rotatable designs with intraclass correlation structure of errors using symmetrical unequal block arrangements with two unequal block sizes

Abstract

In this paper, following the works of Das [11-12], an empirical study on second order slope rotatable designs with intra-class correlation structure of errors using symmetrical unequal block arrangements (SUBAs) with two unequal block sizes is suggested. The variance of the estimated slopes for different values of the intra-class correlation coefficient (ρ) and the distance from the centre (d) for “v factors (6≤v≤12)” are studied empirically.
