WebAug 30, 2012 · The randomized complete block design (RCBD) is a standard design for agricultural experiments in which similar experimental units are grouped into blocks or replicates. It is used to control variation in an experiment by, for example, accounting for spatial effects in field or greenhouse. The defining feature of the RCBD is that each block … WebNote: GLM can not compute standard errors for B and A*B means. Only the standard errors for A means are correct. Use PROC MIXED instead.
