Hi everybody,
I have 56 patients with 5 measurements each (y0,y1, y2, y3, y4). I'using
the xtgee command:
xi: xtgee y i.terapy, family(gaussian) link(identity) corr(exchangeable)
The default reference is y0 and so I obtain the comparison between
y1 versus y0
y2 versus y0
y3 versus y0
y4 versus y0.
I would like to know also the comparison between y4 versus y3 (for
example).
How can I change the reference value from y0 to y3 without changing the
dataset?
Does anybody can help me please?
Thanks a lot,
Paola
