Dear yicaoting!

❝ I will be careful with WNL's BE wizard.


Consider upgrading to Phoenix. It’s free of charge and support for ‘classical’ WinNonlin will end soon. In PHX I have set up a workflow running both the BE wiz and LME. Results are compared and if the difference in both CLs is ≤0.01 % (the magic rounding requirement according to FDA and EMA: 80.00 % ≤ CI ≤ 125.00 %) I use BE’s results. Although fancy stuff is included in WNL (M$-Word export) and PHX (+HTML tables) I never use them. Takes ages to set them up – much easier to import the ASCII-text into a statistical report. ;-)

❝ Your suggestion is definitely valuable if one wants to get high-precision results (at least for 90% CI of the ratio).


If you really bother (and after this this post I’m sure you don’t) and have a lot of money to spare you can obtain a Phoenix Connect-license. Then it would be possible to get the t-value from an R-script.

There’s another point on my wishlist: Have you ever tried to reproduce WNL’s reported power in any other piece of software?

You can get the cheque earlier but then,
of course, it might bounce.    Stephen Senn
