Hi Everyone,
I have a model as
Y~ A + B +E
where A,B are random with different level of F and E is error .
I want to obtain the ration for two within-B standard deviations for two levels of F and 95% CI.
So far I used proc mixed as below code but I don't know how to get the ratio and CI.
Proc mixed data=mydata method=reml:
model Y=;
ods output covparms=cova;
by F;
random A, B;
What option should I put there to get ratio within-B SD_{F1}/SD_{F2} and it CI? Is there any other way?
I appreciate any help.
