% prediction interval and $OMEGA Dear NONMEM users, I am trying to calculate and plot the 95% prediction interval (PI) for a single-subject multiple-dosing PO dataset by simulating 1000 DV values. It seems that bigger initial estimate of omega ($OMEGA) leads to wider 95% prediction band. I understand

Kelong, If you are really and truly only interested in a single subject then the only source of random variability will be the residual error (ERR). I would therefore use the final estimate of OMEGA you obtained from fitting the single subject in order to compute the prediction interval. I
