Comparison of correlation coefficients
Hi,
I calculated a few correlation coefficients. Now I want to know whether
they are different from each other. Is there an R package that can do
such a comparison? Thanks for any suggestion.
Best,

lme question
...it,data=testdata,random=~visit|subject)
I got the following error message.
Error in MEestimate(lmeSt, grps) : Singularity in backsolve at level 0, block 1
In addition: There were 50 or more warnings (use warnings() to see the
first 50)
Could someone give me some hint on what went wrong? Thanks.
