Dear Ace,

Got it! We'll try it again and will report the result back here soon.
Many thanks.

❝ If the C_max may not be included, this explains the difference between the R code and WinNonlin.

❝ If you change

❝ for (i in (nrow(dat)-3):which.max(dat$conc))

❝ to

❝ for (i in (nrow(dat)-3):(which.max(dat$conc)+1))

❝ then C_max is excluded.

❝

❝ And you would get the same result as WinNonlin.

All the best,
