Confidence Interval for a function of variance components.

Do you have the SAS codes for constructing confidence inverval for a function of
Variance components?

Example; If I want to compute the 95% confidence interval for Var(X) + Var(Y)
+Var(Z). and Var(Z) / (X) + Var(Y) +Var(Z).
Either Satterthwaite, Wald or any other method .
Also if intraclass correlation coefficient cannot be greater than 1,can we say same for the first part, i.e.
for Var(X) + Var(Y)
+Var(Z)

Proc mixed data=<> Method=Reml ASYCOVcovtestcl;ClassX Y Z;model A = / ;random X
Y(X) Z(Y);odsoutputcovparms=cov asycov=asycov;run;quit Message was edited by: Saszealot
