I have the following problem ...
I have 5 treatments measured at 7 time
intervals.
How can I answer the following question: "At
which point does each treatment reaches a
plateau?"?
I think this question can be answered by the PROC
GLM procedure in SAS with HELMERT in the REPEATED
statement.
model Y1-Y7 = treatment /nouni
repeated vis 7 helmert / canon printm printe;
Am I right? If yes, how do I interpret the SAS
output? Is there a p-value associated with the
question "At which point does each treatment
reaches a plateau?"?
Thank you,
Martin
