Adjusted Geometric Mean

[SSN_Ravi]

Hi All,

Can you pl let me know how to get adjusted geometric mean?
model is resp as dependent and trt is independent.
And also I need the comparison treatmets (ratio and 95% CI)
Like A:B A:C

Thanks,

This sounds similar to a bioequivalence test. The adjusted geometric means should be the "anti-log" of the adjusted mean (ls-mean) of log transformed values. See the following paper for (hopefully) some help.
