Hi Angus,

» I have repeated the above calculation in NCSS:
Intercept  1.9414  0.2496   0.000025 1.4849      2.3978      9.2
logDose    0.7617  0.0492   0.000005 0.6659      0.8576      5.9


Phoenix/WinNonlin:
           1.9414  0.2431   0.000020 1.4968      2.3860      9.2
           0.7617  0.0473   0.000004 0.6696      0.8539      5.9


Reported by Smith et al. (SAS Proc Mixed):
           1.94                      1.54        2.35
           0.7615                    0.679       0.844


Results by NCSS and Phoenix/WinNonlin are similar but don’t match SAS (whose CIs are wider). I love software.

Cheers,
Helmut Schütz
