Thank`s to everybody who already provided help on this topic.
We used SAS PROC MIXED, as you recomended (but some older version) to
carry the ANOVA with autocorrelated data.
Could somebody help me with these points?
1. What indicates which procedure on calculation of DDDF is appropriate
- the options are KW (Kenward and Roger), Sattertwaith (modification of
KW) and RESIDUALS.
Only the latter one worked properly - MODEL DDFM = Residuals. We used it
just by trial and error, do not understand the differences between the
methods. Can somebody briefly explain?
2. The result of the analysis is just like of normal ANOVA - there is
statistical difference between the groups, i.e. at least one differ from
the others (not very usefull info). Thus I need to carry out some post
hoc test (Duncan, Tukey ...) - is there some way how to do it in the
case of autocorrelated data?
Thank you very much
Tomas
