hi all!
I'm working on a project looking at the effect of an intervention on a continuous outcome variable over time. There are 3 time points. The model I'm using is:
mixed outcome a##time, ||patient ID, noconstant residuals(exch) -->the outcome is displayed below.
Array
I can obtain the overall significance of the interaction using
contrast a#time
However this does not give me an effect estimate for the change in outcome over time. I can obtain the effect of the interaction at the different time points by adding contrast a#time, effect however this does not give me an overall effect estimate for the interaction term to report.
Any thoughts?
Thanks!
