A Statistical Model for the 2-Part Balanced Incomplete Block Design

open access: yesUMYU Scientifica, 2023
Multi-part Balanced Incomplete Block Designs combine many orthogonal balanced incomplete block designs in the same block. The design has been used to study cancer trials with medical centres as blocks. Various design layouts have been constructed for a restricted number of cancer types and drugs.
