Hello,
I am trying to estimate a variance and regression parameters using IML. I used following code to estimate variance matrix R.
PROC IML;
..........
.............
R={1 3 2,4 3 2,5 3 2};
..........
...........
PROC MIXED method=REML;
class Indiv;
model WtLoss = Week;
repeated / type=cs subject=Indiv R;
ods select Dimensions R;
run;
After this part, estimated R needed to be used for making a Block matrix (5 by 5); How can I do this? If anybody know the code for estimating regression parameters (BETA) please let me know.
Any help or advice would be greatly appreciated! Thank you!
