Hi, this is my first post on SAS. I have a split plot design in 5 factors. Factors A, B, and C have 3 levels and are hard to change factors applied to the main plots. Each main plot contains one combination of A,B,C (so 27 main plots in the 3^3 main plot factorial). The sub plot receives a 3^2 factorial in easy to change factors (D, E). Every example I find only discusses how to write the SAS program for Factors A and B. I replicate the entire design twice. I cant find anything on how to adjust the below SAS code to handle 3 factors in the main plot and two factors in the subplots. Simple Split plot in 2 factors: proc mixed;
class A B Block;
model Y = A B A*B;
random Block A*Block;
run; Can someone help or point me in the right direction? much appreciated.
