Anthe,
Sorry about the mistake. You are correct. Of course, the
prediction for DVID.EQ.2 should be ITCL not POPTCL.
Note that you can make the code for prediction of ITCL fancier
if you want e.g. if you have WT then you could make an
allometric prediction. POPTCL would then be the pop TECL for a 70 kg subject.
POPTCL=THETA(2)
GRPTCL=POPTCL*(WT/70)**0.75
ITCL=GRPTCL*EXP(ETA(2)) ; individual prediction for TECL
