CVs for untransformed data [Software]
Hi Zhang Yong,
citing the WNL guide:
One additional parameter will appear in the Final Variance Parameters worksheet if, in addition to using the default model, the data is not transformed:
intrasubject CV = sqrt(Var(Residual)) / RefLSM
where RefLSM is the Least Squares Mean of the reference treatment.
so that's not a bug
For me even the formula above is strange. You are dividing overall standard deviation (calculated for both T and R) by LSMean of reference product only. Does that mean that if we inverse R to T, CV should change too?
