Hi all,
I have a mixed model with Location as fixed, Treatment as random, and Time
as repeated (and within Treatment)
So, I've been using
proc mixed
data=mix1 order=data ;
class Location Treatment;
model yvalue = Location Treatment Time / solution ;
random Treatment(Location)/ sub=Treatment type=cs;
repeated / sub=Time type=cs ;
run;
Now I want to test a cubic trend over time.
proc mixed
data=mix1 order=data ;
class Location Treatment;
model yvalue = Location Treatment Time TimeSqr TimeCube / solution ;
random Treatment(Location)/ sub=Treatment type=cs;
repeated / sub=TimeCube type=cs ;
run;
For the repeated line, should I be stating Time(Treatment) instead of just
Time?
Also, is it fine to put TimeCube in the repeated statement and ignore Timeqr
and Time?
Thanks for any feedback,
