Hi all,
Pl help..
How to do the below nonparametic test in SAS.
Response variable will be compared by nonparametric methods (Brunner, Domhof, Langer 2002).
This will be conducted by including a factor for treatment, time and treatment versus time interaction into the nonparametric repeated measurements model based on rank statistics and considering the hypothesis
H0: No interaction between treatment and time.
data:
PT TRT TIME RESP
-------------------------------------
01 trt1 week1 20
01 trt1 week2 50
02 trt2 week1 35
02 trt2 week2 55
