Penghitungan semua JK (SS) seperti pada simple split plot. Kecuali untuk errornya. Erlina Ambarwati
ANOVA Erlina Ambarwati PROC GLM; CLASS BLOCKS TREATS CROSS; MODEL WHATEVER = BLOCKS TREATS BLOCKS*TREATS CROSS CROSS*BLOCKS CROSS*TREATS; TEST H=BLOCKS TREATS E=BLOCKS*TREATS; TEST H=CROSS E=CROSS*BLOCKS; RUN;
RCB repeated in time • Field marks: • Multiple measurements of the same experimental subjects are made in time. • Treatments are assigned at random within blocks of adjacent subjects, each treatment once per block. • The number of blocks is the number of replications. Erlina Ambarwati

RCB repeated at more than one location Field marks: • Blocks are laid out at more than one location. Treatments are assigned at random to those blocks as below. • Treatments are assigned at random within blocks of adjacent subjects, each treatment once per block. • The number of blocks is the number of replications. • Any treatment can be adjacent to any other treatment, but not to the same treatment within the block.
