Hi,
I have a question on how to analyse an exprimental design.
We had three treatments (C, T, M) of which only two could be
administred to each subject. The subjects receieved those treatments
in two weeks following each other (W1, W2). I total there were six
experimental groups, each defined by a treatment combination, i.e.
grp w1 w2
1 C T
2 C M
3 T C
4 T M
5 M C
6 M T
We are interested in comparing the effects of treatments, e.g. C vs M.
Right now I am considering a repeated measures analysis, with week and
grp as factors. However, I cannot figure out how to compose the
contrasts that would answer our questions.
Any hints? Is there some other, conceptually easier approach I could
take? Any litterature on this?
Best regards,
Kasper Hornb�k
