How to control for within-subject independent variable

[rlking]

Hello,

I'm using a repeated GLM for the same behaviour measure of each subject over three consecutive days which goes something like this:

proc glm data = x;

class treatment;

model behaviour1 behaviour2 behaviour3 = treatment;

repeated days 3;

run;

My problem is that some of the days are on the weekend which will affect the behaviour, so how can I control for the effect of weekend? (which I've recorded as binary 1/0 for each day). Fit it into the repeated statement somehow??

Better try PROC MIXED or PROC GLIMMIX for repeated measure.

Check the examples in documentation.
