Dear collegues,

I have a question:

I have calculated the adjusted means with Anova command:

anova y g z, continuous(z)
adjust z, by(g)
groups xb
0 1068,04
1 1027,86
2 1309,4
Key: xb = Linear Prediction

adjust z
All xb
1027,86

Is it correct ? I need the all mean, which is the command ?

I need the IC and SD of the adjusted means, how can I calculate them ?

where y = continuous variable (colesterol)
g = groups
z = the variable used to adjust (creatinine)


Thanks a lot to everybody,

Rachele
