On the block structure of PBIB designs

M. L. Chandak

International Journal of Mathematics and Mathematical Sciences, 1980, vol. 3, 1-7

Abstract:

Let { θ , θ 1 , … , θ n 1 } denote the set having any treatment θ and its n 1 first associates in a PBIB design with m ( ≥ 2 ) associate classes. A theorem on distribution of the elements of this set among the blocks of the block design is proved and results related to certain well known association schemes of three associate classes are obtained.
