Series4: Tri-Hierarchical IBDs using Initial Block Solution
Description
This function gives Tri-Hierarchical IBDs using initial sequences. Here, v = 4t+1 or 4t+3, where t is an integer and v should be a prime number, using primitive element of Galois field designs are generated. We find balanced incomplete block designs (BIBD) at block level and PBIB designs at sub-block level as well as sub-sub block level with circular association scheme. Information matrix pertaining to the estimation of treatments effects, canonical efficiency factor in comparison to an orthogonal design and six component designs are provided.
