    Are you able to please confirm my understanding of the postestimate "iccvar" command proceeding xtmixed.

    I want to assess the correlation between two continuous variables (both serum markers) over three time points in a cohort of 50 patients.

    I have used xtmixed to see if they are significantly correlated which they are but want to see how tightly. I then ran the iccvar command and the output gave me a value for ICC. I am wondering if this is the correlation coefficient between the two continuous variables? IF not can you suggest how I obtain this?

    Hello Megan,

    Thanks for commenting. Sorry for the delay in replying - I saw this comment only now. I see that you have posted a question to the statalist and the answer is now in the statalist archives.

    Cheers,
