Dear Christine
I think the problem in your second model is that you are

You have two and only two individuals per dyad; when you try to fit random
slopes at level-2 (within couples), you are attempting to estimate an
intercept,
slope, and covariance for each individual. Basically, you don't have enough
data to do it. If you restrict yourself to a
Hi,
I am trying to run a multilevel model with time nested in people and
people nested in dyads (3 levels of nesting) by initially running a
series of models to test whether the slope/intercept should be fixed or
random. The problem that I am experiencing appears to arise between the
random
