Hi ElMaestro,

» If someone reports a CI of 0.8456-1.0000 to me, then it might in actuality imply a 90% CI of 0.8456-0.98765 or whatever. Is that science?

As zizou noted above it is less informative than the conventional (shortest) CI – we only know that the GMR is <1 – and we can’t calculate the CV from the CI any more.

» Why not just go all the way and adjust all CI's so that they span across 1.0 like...what was his name... some statistician twenty-thirty years ago.... his name was Lester Hamsterballs or something...?

41 years ago. Westlake. Wilfred J. Westlake.

Took me ages to persuade Pharsight/Certara to remove it from the standard output of WinNonlin (available till v6.3).
